What is delay-buffer-rate in JUNOS COS?
I have been hitting my head, googling it but there is no much info about what it is really and how it differs from delay-buffer size concept.
Any one the form really knows the purpose of this knob and what it really is.
Much appreciated!!

How to apply tracking condition to static route definition EX switch
Hi guys,
I have an EX4600 and I would need to apply a tracking condition to some static routes configured on it, based on the status of 1 EX physical interface, like another manufacturers can do...
Do you know if is this possible with an EX? I am looking in the command guide but I cannot see similar function
Kind Regards
Juan

juniper self study guide worth it
Hi,
I have just passed my JNCIP-SP and want to make a start towards the LAB. I have been looking for materials, Juniper's self study guide is obviously the first thing that comes up. $600 seems pretty steep if it just basically a book. or is the mock exams that come with it that make it worth it?
I guess what I am asking whats in it? :-)
PS. i mean worth it if you decide that you want to do the exam, I have already decided on that, as I have been working in ISP networking for a long time and just want to get this accreditation for my own satisfaction

JNCIE-SP/VPNs/Layer 3 VPNs/6PE
My vMX version: 17.4R1.16
Greetings, I have configured the example above exactly as given, except I used ge interfaces specific to my home lab. I am unable to ping CE2 @ ::192.0.1.5 from CE1 ::192.0.1.1. Can somebody please answer the following questions?
- Is there an error in the example where I would not be able to ping without corrective configuration?
- Is this example useful as prep for the 6PE topic on the JNICE-SP exam?
- What show commands on what devices would be best for me to post in order to troubleshoot this issue?
Thanks.

Don't Label Me Bro - Juniper Edition
My MPLS post the other week was pretty well received so I figured might as well show the other side of the coin and do it again with Juniper boxes.
#Topology
Today's Topology is similar to last time but Juniperified, we have:
- 4 x PE routers that are vMX
- 4 x P are vSRX
- 4 x CE routers are VSRX boxes as well.
There are again two customers, CUST-A and CUST-B because originality is hard.
To save on some config space I'll just focus on a single router at a time unless there is differences that are worth seeing.
#Provider Routers
###Disable Flow Mode
I'm using SRX routers for my core so we need to disable the default flow based mode and reboot the boxes before we can use them with MPLS.

root@P01# set security forwarding-options family mpls mode packet-based

root@P01# set security forwarding-options family iso mode packet-based
root@P01# commit
commit complete
[edit]
root@P01# run request system reboot
Reboot the system ? [yes,no] (no) yesOnce this is done we will no longer need to use security zones for everything.
###Basic Setup
To keep things clean I'm using a virtual-router instance to move the first interface into another routing table for management.
set routing-instances MGMT instance-type virtual-router
set routing-instances MGMT interface ge-0/0/0.0
set routing-instances MGMT routing-options static route 0.0.0.0/0 next-hop 10.20.2.1
set interfaces ge-0/0/0 unit 0 family inet address 10.20.2.211/24Most of my interfaces are connecting to trunk ports to make life easier so I'm going to enable vlan tagging and use subinterfaces to connect to everything.
set interfaces ge-0/0/1 vlan-tagging
set interfaces ge-0/0/1 unit 3011 vlan-id 3011
set interfaces ge-0/0/1 unit 3011 family inet address 10.1.11.1/24
set interfaces ge-0/0/1 unit 3012 vlan-id 3012
set interfaces ge-0/0/1 unit 3012 family inet address 10.1.2.1/24
set interfaces ge-0/0/1 unit 3013 vlan-id 3013
set interfaces ge-0/0/1 unit 3013 family inet address 10.1.3.1/24
set interfaces ge-0/0/1 unit 3014 vlan-id 3014
set interfaces ge-0/0/1 unit 3014 family inet address 10.1.4.1/24
set interfaces lo0 unit 0 family inet address 192.168.255.1/32Then I'll just turn on OSPF on all active interfaces in the routing instance.
root@P01# set protocols ospf area 0.0.0.0 interface all Once we are done we should see a neighbor with every other P router and a PE router (once we get that far)
root@P01# run show ospf neighbor
Address Interface State ID Pri Dead
10.1.11.254 ge-0/0/1.3011 Full 192.168.255.11 128 39
10.1.2.2 ge-0/0/1.3012 Full 192.168.255.2 128 32
10.1.3.3 ge-0/0/1.3013 Full 192.168.255.3 128 39
10.1.4.4 ge-0/0/1.3014 Full 192.168.255.4 128 34###Enabling MPLS
While Cisco put effort into making sure MPLS is turned on right away, Juniper takes a bit more effort.
First we need to enable MPLS and LDP in the control plane under protocols, we can conveniently use the interface all keyword to enable it on all interfaces.
root@P01# set protocols mpls interface all
root@P01# set protocols ldp interface all Next we need to turn it on for the forwarding plane by adding the mpls family to each interface on the router that will be in the MPLS path. This can be a bit annoying so you might want to look into things like config groups to ease the admin burden.
set interfaces ge-0/0/1 unit 3011 family mpls
set interfaces ge-0/0/1 unit 3012 family mpls
set interfaces ge-0/0/1 unit 3013 family mpls
set interfaces ge-0/0/1 unit 3014 family mpls
set interfaces lo0 unit 0 family mpls#Route Reflector
We'll use a route reflector again but this time I'm just take advantage of the logical-system feature to carve PE01 and PE02 into two new Route Reflector boxes.
###RR01
First we'll turn on vlan-tagging for the interface I want to use since we still need to configure physical stuff at the interface level in logical-systems.
root@PE11# set interfaces ge-0/0/2 vlan-tagging Next we configure the interfaces like above under the logical-system.
root@PE11# set logical-systems RR01 interfaces ge-0/0/2 unit 3123 vlan-id 3123
root@PE11# set logical-systems RR01 interfaces ge-0/0/2 unit 3123 family inet address 10.0.123.254/24
root@PE11# set logical-systems RR01 interfaces ge-0/0/2 unit 3123 family mpls
root@PE11# set logical-systems RR01 interfaces lo0 unit 1 family inet address 192.168.255.154/32
root@PE11# set logical-systems RR01 protocols ospf area 0.0.0.0 interface all
root@PE11# set logical-systems RR01 protocols mpls interface all
root@PE11# set logical-systems RR01 protocols ldp interface all BGP is configured with the inet-vpn family which is the same as Cisco's VPNv4 family, the route reflector will have all for PEs as a peer, will use 65123 as the AS for iBGP and will set a cluster-id so Juniper knows it is a Route Reflector.

root@PE11# set protocols bgp group RR neighbor 192.168.255.254 #VRF / Policies
Now our BGP is up it is time to create the last piece of the L3VPN and which is making the policies as well as the VRF the CE goes into.
###Policies
In Cisco land we controlled what route we imported and exported under the VRF configuration, Juniper does that too but for more granular control we will make a more elaborate policy.
First we make an community policy that just exports the PE's RD on each router.
root@PE11# set policy-options community RT-EXPORT-CE01 members target:65123:101 Next we'll do the same for the import community where we will make one for each CE for flexibility's sake.
root@PE11# set policy-options community RT-IMPORT-CE01 members target:65123:101
root@PE11# set policy-options community RT-IMPORT-CE02 members target:65123:102
root@PE11# set policy-options community RT-IMPORT-CE03 members target:65123:103
root@PE11# set policy-options community RT-IMPORT-CE04 members target:65123:104With that in place we make a policy that will become our VRF-Export policy, we will say that if the protocol is directly connected or one of the routing protocols then we will add the export community and accept the route.
root@PE11# set policy-options policy-statement EXPORT-CE01 term EXPORT from protocol [ direct bgp rip ospf ]
root@PE11# set policy-options policy-statement EXPORT-CE01 term EXPORT then community add RT-EXPORT-CE01
root@PE11# set policy-options policy-statement EXPORT-CE01 term EXPORT then accept If it doesn't match that criteria then we will reject it.
root@PE11# set policy-options policy-statement EXPORT-CE01 term REJECT then reject The VRF-Import policy will always be from MBGP so we match on protocol BGP, then we select what communities we want to talk to each other.
In our topology Cust-A is CE01 and CE02 so we'll do that then reject the rest.
root@PE11# set policy-options policy-statement IMPORT-CE01 term IMPORT from protocol bgp
root@PE11# set policy-options policy-statement IMPORT-CE01 term IMPORT from community [ RT-IMPORT-CE01 RT-IMPORT-CE02 ]
root@PE11# set policy-options policy-statement IMPORT-CE01 term IMPORT then accept
root@PE11# set policy-options policy-statement IMPORT-CE01 term REJECT then reject###VRFs
With all that in place we need to make a VRF instance. In my case I'm using ge-0/0/5 on all the PEs as the CE interface so we add it to the VRF, we also set the PE's proper RD and apply the VRF policies we just made. We also use vrf-table-label to help make the L3VPN happy.
root@PE11# set routing-instances CE01 instance-type vrf
root@PE11# set routing-instances CE01 interface ge-0/0/5.0
root@PE11# set routing-instances CE01 route-distinguisher 65123:101
root@PE11# set routing-instances CE01 vrf-import IMPORT-CE01
root@PE11# set routing-instances CE01 vrf-export EXPORT-CE01
root@PE11# set routing-instances CE01 vrf-table-label We'll also set the router-id for the instance just to have a bit more control
root@PE11# set routing-instances CE01 routing-options router-id 192.168.255.11 #Customer Edge
###PE01
Finally we will start working on the CE routing!
We need an export policy so Juniper knows what to send so I'll make a simple one that just accepts any route, since PE01 is BGP we'll setup that too. The config is the same as you have seen though you may want to use the as-override option if you are using BGP.
root@PE11# set policy-options policy-statement EXPORT-BGP then accept
root@PE11# set routing-instances CE01 protocols bgp group CUST-A type external
root@PE11# set routing-instances CE01 protocols bgp group CUST-A export EXPORT-BGP
root@PE11# set routing-instances CE01 protocols bgp group CUST-A peer-as 65101
root@PE11# set routing-instances CE01 protocols bgp group CUST-A neighbor 192.168.1.1 as-override
root@PE11# set policy-options policy-statement EXPORT-BGP then accept
root@PE11# set policy-options policy-statement EXPORT-OSPF from protocol bgp
root@PE11# set policy-options policy-statement EXPORT-OSPF then accept
root@PE11# set policy-options policy-statement EXPORT-RIP then metric 5
root@PE11# set policy-options policy-statement EXPORT-RIP then accept ###CE01, CE02, CE03, CE04
Since the CE's are still in flow mode, we need to make sure the interfaces we use are trusted by the security zone, we could get more specific but we aren't really playing with the firewall today :)
root@CE01# set security zones security-zone trust host-inbound-traffic system-services all
root@CE01# set security zones security-zone trust host-inbound-traffic protocols all
root@CE01# set security zones security-zone trust interfaces ge-0/0/1.0
root@CE01# set security zones security-zone trust interfaces ge-0/0/2.0 ###CE01
For BGP we just do a normal peering and advertise everything directly connected.
root@CE01# set policy-options policy-statement EXPORT-BGP from protocol direct
root@CE01# set policy-options policy-statement EXPORT-BGP then accept
root@CE01# set protocols bgp group CUST-A type external
root@CE01# set protocols bgp group CUST-A export EXPORT-BGP
root@CE01# set protocols bgp group CUST-A peer-as 65123
root@CE01# set protocols bgp group CUST-A neighbor 192.168.1.254 ###CE02
Same with RIP for CE02
root@CE02# set policy-options policy-statement EXPORT-RIP from protocol direct
root@CE02# set policy-options policy-statement EXPORT-RIP then accept
root@CE02# set protocols rip group CUST-A export EXPORT-RIP
root@CE02# set protocols rip group CUST-A neighbor ge-0/0/1.0 ###CE03 and CE04
The OSPF CE is a bit unique because it is the only protocol we are looking at today that cares about external routes. Let's setup OSPF in two ways, one will simply add all interfaces to OSPF and the other will use the export method we have been doing
root@CE03# set protocols ospf area 0.0.0.0 interface all
root@CE03# set protocols ospf area 0.0.0.0 interface lo0.0 passive
root@CE04# set policy-options policy-statement EXPORT-OSPF from protocol direct
root@CE04# set policy-options policy-statement EXPORT-OSPF then accept
root@CE04# set protocols ospf export EXPORT-OSPF
root@CE04# set protocols ospf area 0.0.0.0 interface ge-0/0/1.0 Now we get the routes but routes from CE04 are external! We might talk about OSPF specific MPLS topics another day!
root@CE03# run show ospf route

JNCIE Study
So, since we need to kick this subreddit to life again - who here is preparing for any JNCIE lab or even the JNCIP written exams?
There are few JNCIEs here that are very willing to help in any way we can.
Just trying to spread the Junos love.

JNCIE-SEC blueprint question
Starting to give it some more thought in persuing JNCIE-SEC, one thing I saw on the blueprint is BGP, OSPF and some other routing stuff. My question is do I need to learn this at a JNCIE level or is JNCIS/JNCIP level fine? I've done all the formal training for SRX but never came across any routing modules.

Routing Engine Redundancy:
set chassis redundancy failover on-disk-failure
set chassis redundancy failover on-loss-of-keepalives
To change the keepalive time period:
Set chassis redundancy keepalive-time
For a process failire failover:
set system processes process-name failover other-routing-engine
set system processes routing failover other-routing-engine
GRES:
Set chassis redundancy graceful-switchover
Set system commit synchronize

Nonstop bridging
set protocols layer2-control nonstop-bridging
Nonstop Routing
set routing-options nonstop-routing
Nonstop routing and graceful restart can not be configured at the same time.
Graceful Restart:
Gaceful restart is disabled by default.
set routing-options hierarchy graceful-restart
configure the duration of the graceful restart period:
set routing-options graceful-restart restart-duration
Helper mode is enabled by default. You can disable helper mode on a per-protocol basis.
set the length of time the router waits to receive messages from restarting neighbors:
set protocols bgp graceful-restart stale-routes-time
Restrict OSPF link-state advertisement (LSA) checking:
set protocols ospf graceful-restart no-strict-lsa-checking
To configure the delay between when the router discovers that a neighboring router has gone down:
set protocols rsvp graceful-restart maximum-helper-restart-time
For Layer 3 VPNs only, you must also configure graceful restart for all routing and MPLS:
set routing-instances instance-name routing-options graceful-restart
VRRP
To configure the startup period for VRRP operations, include the startup-silent-period
statement at the [edit protocols vrrp] hierarchy level:
To configure basic VRRP for IPv6 support, configure VRRP group support on interfaces
by including the vrrp-inet6-group statement:
vrrp-inet6-group group-id {
priority number;
virtual-inet6-address [ addresses ];
virtual-link-local-address ipv6-address;
}
authentication can be simple or md5.
To modify the time, in seconds, between the sending of VRRP advertisement packets,
include the advertise-interval statement
Passive ARP learning enables the ARP cache in the backup router to hold approximately
the same contents as the ARP cache in the master router, thus preventing the problem
of learning ARP entries in a burst. To enable passive ARP learning, include the
passive-learning statement at the [edit system arp] hierarchy level

OAM theory and config
Fault detection and notification (provided by continuity check messages)
The target MAC address is learned by the
continuity check protocol or linktrace protocol
Each maintenance domain is associated with a maintenance domain level from 0 through 7.
where outermost domains are assigned a higher level than the innermost domains.
maintenance domain, each service instance is called a maintenance association.
A maintenance association ca nbe thought as a full mesh o fmaintenance endpoints (MEPs)
(MIPsonly respondto CFM messages
The continuity check protocol packets use the ethertype value 0x8902 and the multicast destination MAC address 01:80:c2:00:00:32.

Alternate multicast routing table:
If asked to change how multicast is forwarded or its knowledge of the shortest path, and if you can't create a static route, then you must use inet.2. Put your routes into inet.2, and then tell PIM to use inet.2.
Create a rib-group to copy ALL inet.0 routes to inet.2:
set routing-options rib-groups Copy-inet0-to-inet2 import-rib [ inet.0 inet.2 ]
set routing-options interface-routes rib-group inet Copy-inet0-to-inet2
set protocols (isis|ospf) rib-group Copy-inet0-to-inet2
set protocols bgp group Group-Name family inet rib-group Copy-inet0-to-inet2
Create a different rib-group pointing to inet.2 for reference by PIM:

BGP Tips
show route aspath-regex (regex)
Practice using SecureCRT, not Putty.
BGP default policies: Import: Accept all routes if BGP can resolve their BGP next-hops. Export: Advertise the best active BGP routes. (If an IGP shadows the BGP route, it will be inactive and not advertised.)
For hidden BGP routes: Routes are hidden because their next hops can't be resolved or due to policy filtering. show route hidden show route resolution unresolved (unresolvable routes only)
Remember to set next-hop self when importing routes from EBGP neighbors. Don't do this for any other reason, not even at route reflectors.
set protocols bgp traceoptions file BGP-Trace.log set protocols bgp traceoptions flag update detail
BGP troubleshooting: Avoid troubleshooting if at all possible. Make sure BGP sessions are established. Ensure needed protocol families are configured under BGP AND negotiated. Check if routes are advertised and received. Look for unresolved routes. Verify routes are in the routing tables. Use specific show commands with filters. Use traceoptions only for difficult problems. If you get stuck on something unfamiliar, consider moving on and coming back to it later.

IS-IS Troubleshooting
Neighbor establishment:
Mismatched area IDs for a level-1 adjacency.
Incorrect IP addresses.
One in broadcast mode, one in point-to-point mode.
Family ISO missing from interfaces.
Interfaces down.
Interface is passive, has wrong level, or is disabled.
Family ISO MTU must be >1492.
So physical MTU must be 1506 or higher?
MTU mismatch:
Not really a problem for IS-IS?
Physical - 14 = inet or inet6 MTU.
1514 is default GE MTU.
Router IDs:
Duplicate system IDs.
Authentication:
Bad hello authentication config.
Routing loops:
Use traceroute to diagnose.
Usually happens at redistribution points.
Summarization:
Incorrect criteria: from protocol, from level, to level
Incorrect actions: reject instead of accept

IS-IS Implementation
Configuration:
set interfaces lo0.0 family iso address 49.0001.1921.6801.2001.00
set protocols isis reference-bandwidth 100g
set protocols isis interface ge-0/1/2.0

set interfaces ge-0/1/2.0 family iso
or: set groups Family-ISO interfaces <ge-> unit 0 family iso
set groups Family-ISO interfaces <ae> unit 0 family iso
set interfaces apply-groups Family-ISO
Router advertisement:
set protocols isis interface ge-0/1/2.0 priority 0 (don't become DIS)
or: set protocols isis interface ge-0/1/2.0 point-to-point (removes DIS)
Routing policy:
set protocols isis export [ Level2-Leak Level1-Leak-Aggr-20 Level1-Leak-Exact-20 Export-Direct Export-Static ]
set policy-options policy-statement Level2-Leak term 1 from route-filter 1.2.3.4/32 exact
set policy-options policy-statement Level2-Leak term 1 from level 2
set policy-options policy-statement Level2-Leak term 1 to level 1
set policy-options policy-statement Level2-Leak term 1 then tag 1234
set policy-options policy-statement Level2-Leak term 1 then accept
set policy-options policy-statement Level1-Leak-Primary-20 term 1 from route-filter 20.20.20.0/24 exact
set policy-options policy-statement Level1-Leak-Primary-20 term 1 from level 1
set policy-options policy-statement Level1-Leak-Primary-20 term 1 to level 2
set policy-options policy-statement Level1-Leak-Primary-20 term 1 then tag 20
set policy-options policy-statement Level1-Leak-Primary-20 term 1 then accept
set policy-options policy-statement Level1-Leak-Backup-20 term 1 from route-filter 20.20.20.1/32 exact
set policy-options policy-statement Level1-Leak-Backup-20 term 1 from level 1
set policy-options policy-statement Level1-Leak-Backup-20 term 1 to level 2
set policy-options policy-statement Level1-Leak-Backup-20 term 1 then tag 21
set policy-options policy-statement Level1-Leak-Backup-20 term 1 then accept
(By default, IS-IS doesn't leak level 1 external routes (20.20.20.0/24) into level 2 unless wide metrics are used.)
IPv4 and IPv6 support:
This is built in.
BFD:
set protocols isis interface ge-0/1/2.0 bfd-liveness-detection minimum-interval 300
Load balancing:
set routing-options forwarding-table export Load-Balance-All
set policy-options policy-statement Load-Balance-All then load-balance per-packet
Optimize timers:
set protocols isis interface ge-0/1/2.0 level 2 hello-interval 2
set protocols isis interface ge-0/1/2.0 level 2 hold-time 8
(DRs are set to one-third of these configured values.)
CSPF support:
This is built in.
Authentication:
set protocols isis level 2 authentication-type md5
set protocols isis level 2 authentication-key Blah
set protocols isis interface ge-0/1/2.0 level 2 hello-authentication-type md5
set protocols isis interface ge-0/1/2.0 level 2 hello-authentication-key Blah
Metrics:
set protocols isis level 2 narrow-metrics-only (default)
set protocols isis level 2 wide-metrics-only
Overload:
set protocols isis overload timeout 60 (for 60m after a reboot)

OSPF notes Day 1
24 octect header version, type, checksum, authentication, auth type, Router ID, Area ID, packet length.
Hello Packet mask, hello interval*, options*, router priority, dead interval*, DR, BDR, neighbours
Database Description MTU, options, flags, Bit 2, The I bit determines the first packet. Bit 1, The M bit determines the last packet. Bit 0, The M/S bit. Master is bit 1. Slave is bit 0. DD sequence number, LSA headers.
Link State Request LSA type, link state ID, Advertising router.
Link state update number of LSAs, LSA advertisements.
Link state ack LSA headers.
Down - no ospf Init - received hello Attempt - only for NBMA, router will send hello 2 way - hello received with own router ID Exstart - Master/Slave chosen Exchange - DD are sent Loading - if missing LSA then LSR sent Full - OSPF adj up
Designated Router 224.0.0.6, type 2 LSA Router Priority then Router ID
Wait time 40 seconds before the DR is elected so all routers have a chance. Non deterministic(if DR goes down it does not necessarily become DR again).
Summary LSA, Type 3 Matches a single router LSA.
External LSA, Type 5 Domain wide flooding ABR creates a type 4 LSA for each type 5.
Stub Area ABR enforces stub type 3 summary LSA injected to stub
Totally stubby only one default type 3 LSA injected.
Not So Stubby Type 7 LSA for external routes ABR converts to typr 5 LSA and floods.
"clear ospf database purge" set all LSA to 3600 MaxAge timer and flood.
Intra-area then inter-area then external
Junos allows to restrict type 3 LSAs in NSSA using no-summaries
prefix-export-limit to limit number external prfixes allowed
set reference bandwidth
Common LSA header: Link state age, LSA type, Link state ID, Advertising router, Link state, Checksum, lenght
Router LSA: V, E, B, # of links, metric,
show ospf database router area 0 external asterisk is for LSA sent by local router
The act of turning the type 7 to a type 5 makes it a ASBR.
Router build tuples for spf.
link state database: contains tuples candidate database:cost from root to neighbot tree database:contains shortest path
Restart candidate, possible helper, helper. Type 9 LSA. disable helper-disable.
An ABR does not make a type 3 LSA from another type 3 LSA.

type 1 increases the metic based on the cost to the adverting router type 2 default.
