I have 2 months to renew. what is the easiest way to renew?

Hi

https://ibb.co/k4FhfHd

If LSR2 received 4 LDP binding updates from a different LDP peers , which one LSR1 is going to choose and why?

LDP is used for two things:-

1-for assign a local label for each subnet in the routing table except bgp routes

2-for advertise these label binding to the other LDP peering.

the question here is how the LDP knows the best route in the routing table? does LDP look in the routing table?

let`s talk first about the control plane.

any device do two things, first he learn then he forward.

we are now on LSR2. this box received in the control plane 4 IGP routing updates and then received 4 LDP binding updates.

all routers are using EIGRP for simplicity.

LSR2 is going to choose the best EIGRP route.

but how the LDP is going to choose the best LDP label? we talked about this point and i said the LSR is choosing the best label depend on the best IGP route. and now the question is, how LDP knows the best route? is there a hidden relation between the IGP and LDP?

please don`t talk about the data plane now and just focus on the control plane.

each protocol select the best route and the best label. that is what i know. if eigrp is a protocol and LDP is also a protocol so the protocol is doing this behavior select the best thing he has and then use it in the data plane for forwarding.

With the cyber Monday sale going on, is the skilldive subscription worth the cost or is the premium “good enough”?

For reference, I plan on sitting for the ENARSI in the next two months and taking my first attempt at the CCIE EI in Q3 of 2025.

I'm planning to attempt the ccie lab in Tokyo next month, if anyone attempted the lab in Tokyo recently kindly share your general experience.

Specially I read a lot of fuss about keyboard being Japanese variant in the lab, so whats the actual deal.

Hi,

I'm a Japanese CCNP holder and considering to take CCIE EI v1.1 Lab exam now.

BTW I've heard about something as title written.

I'm afraid that the same question might be asked during short period.

In the case of I don't want to use dump in terms of ethical, is retaking the only way to pass the exam early and save my money?

and even if I take the exam in 6 month intervals, don't the pass rate vary compared to in shorter intervals,right?

Hello

LSR1 <---->LSR2<--->LSR3<--->LSR4<--->LSR5<--->LSR6

1.1.1.1/32 2.2.2.2/32 3.3.3.3/32 4.4.4.4/32 5.5.5.5/32 6.6.6.6/32

here we have 6 routers are running LDP 6 LSRs. is that mean we have only one LSP in the entire network OR we have unlimited number of LSPs ? if LSR1 wants to reach to 2.2.2.2/32 is that a separate LSP and if LSR1 wants to reach to 3.3.3.3/32 is that a 3rd LSP etc ? OR we only have one LSP ? which is correct and why?

Hi

the MPLS header has a label field which is used for label range . the size is 20 bit which means 2^20=1048576 . but what if this number is not enough? for example in IPv6 we have about 4 billions of IPv6 addresses. what is going to happened in this case?

thanks

I've been invited to apply for the CCIE Advisory Council 2025. Does everyone who's got a CCIE get this invitation? What's that actually all about? Is it worth applying? Many thanks in advance for sharing your experiences and opinions.

This is something I've for the ENCOR; it's awesome. But is there something similar for the CCIE?

Hello, Im a 27 y.o engineer. Im in this industry about 3-4 years as a design engineer of a large bank. Mostly responsible of WAN designs of DCs, branches, HQs etc. Im currently holding 2xccnp, even this makes me feel I carry more knowledge than my hands on experience. Most people around me with CCIE about 32-40 years old. This makes me feel i still have long way to go before prepare for CCIE. Am I thinking wrong about this?

I searched through this sub to see if someone posted this question already. But, is the lab the same every time you take it? Other than version updates of course. I'm just wondering if it changes from one attempt to another.

what is the difference between:-

show mpls ldp binding

vs

show mpls ip binding

I am going to take the Micronics Training CCIE IE course online. Do you have any recommendations on what to expect? Do they use Webex for the live discussions? And little details will help

I took my Security exam a couple of months ago and had done way worse on it than I had thought especially in the design. When going through the design it felt like they asked things I wouldn’t normally think about when I design things. Since then I’ve reviewed quite a few SAFE documents again just trying to see if I could find a doc that would answer a couple of questions I remembered but nothing seems to be a direct good answer. The design section at least pointed out a couple things I needed to work on with APIs and programmability, but even some of their wording for other questions I think I took to literally, and I chose a different answer because it wasn’t what is the actual option available in a drop down.

Then onto the lab I mean for the most part everything on there didn’t seem terribly difficult to build but I ended up jumping around. Which caused me to almost skip some things, and then causing myself to feel overwhelmed and then doing terribly. So now here I am studying and labbing more in preparation for my next attempt which I’ve booked for next month, but for the design part I feel like I don’t know what is a good resource to try and use for study material. I’ve went and bought the CCDE book but it seems to high level and would really like some recommendations for where and what to read for it. As for the lab I think I just need to slow down and take it one task at a time and not jump around since everything on it I didn’t feel like I couldn’t do it besides maybe a couple oddly worded or things that just seemed to be impossible to know off the top of your head without looking at a document.

Sorry for the ramble/rant but if anyone has any recommendations or insight for my next attempt I would greatly appreciate it.

Can someone suggest?

Hey all, I am an EA helping the Network Engineer I support work on certifying himself further for our company. He is wanting to obtain his CCIE Security.
He has asked me to come up with a learning path and plan (along with budget) so we can submit to the company for partial reimbursement and budget in time into his schedule to ensure he has some study time during the work day too.

The downside, this is not my industry. I have no idea what I'm looking at. I am on Cisco's website and I've found a few bootcamps via google but from what I have read here, its more complicated than that?

Has anybody put together a comprehensive breakdown or even a suggested learning path?
I know I know, my NE should be the one doing this but he's asked me to do it. so now its my job.
Help a girl out?

Hi Guys,

I was upgrading cisco9k to 10.3.5 from 9.3.5 and after the upgrade l2 ports got suspended by vpc as keep alive links were not coming up. To fix that, i tried cable/sfp swap and bouncing the port but it didn't come up and to fix this issue i moved the peer links to different ports on both the peers and as we configued the ports we started getting mac moves and duplicate host logs on the device as it was not added in the port-channel yet and once i added it back in port-channel those logs stopped but server teams reported issues as around 200 vms got rebooted or got stuck in read only mode. Can someone suggest if anybody has seen similar issues or can these duplicate host l2rib is a sign of any kind of issues which can cause major outages.?

10 Years Baby!

I took my exam in October and failed. This was my first attempt since I started my career in 2018. I need your expert advice on how to cope with pressure of the exam preparation alongside work. I haven't implemented or worked extensively with DMVPN and MPLS technologies since I'm doing more work on the L2 level. I guess I need more knowledge on the theory of how things work and improve troubleshooting skills.

Extremely depressed right now. Please let me know how can I upskill my technical knowledge. Need to make a difference with being a CCIE and rather not just having it.

Sisters and Brothers in networking. I got the following email from Cisco:

We’re about to announce the latest features for Cisco Modeling Labs v2.8 release. But before we let the rest of the world see, we want to give you a sneak peek of the following new helpful features and more:

Smart annotations: Quickly create organized topologies. NGFW enablement: Use Firepower Threat Defense Virtual (FTDv) and Firepower Management Center Virtual (FMCv) out of the box . Custom MAC address: Create assigned MAC addresses that align with their existing physical networks. LDAP improvements (Enterprise | Education editions):  Allows Lightweight Directory Access (LDAP) users to map LDAP groups to Cisco Modeling Labs groups so users get the right access the first time they login to Cisco Modeling Labs. Save the date and register for Cisco Modeling Labs v2.8 virtual event, on Tuesday, November 12, 2024, at 9:00 a.m. Pacific Time.

It seems like CML is expanding to quite the capability (besides the node limit lol).

With the Custom MAC Address, does this address the issues with the CAT9Kv?

And has anyone played with deploying organic SDWAN in CML 2.7 vice the Frankenstein method in say EVE or GNS3?

And Does anyone know if you can integrate Nexus Dashboard with the N9K image to create a sudo Fabric?

I’m just excited for what the platform is becoming. Definitely renewing my subscription on Cyber Monday.

I'm at a crossroads in my career after being laid off recently. I've been doing Collab my entire career, but the industry is rapidly changing. I have my CCIE Collab and have been doing this since CUCM 4.x. To stay relevant, I've gotten my DevNet Associate and taken some Microsoft 365 classes .Now, I'm trying to decide if I should continue down the same path and focus more on DevNet or Microsoft or completely switch things up and study to become an AWS solutions architect, which I'm leaning toward. I hope my experience will help me pursue a new technology area, but I realize I'll have to start from the bottom. I'd appreciate any insights or advice you have on this change or if you think I'm crazy for considering leaving the Collab world. Thanks in Advance.

Over a decade ago the go to video training were IP Expert and INE. Probably 8-9 years ago, INE pieced together videos from different tracks to update a current track at the time. This was fine but it bothered me because the trainer were different. I don't know how INE build their training CCIE tracks these days. I also read the quality was going downhill. Jeremiah Wolfe didn't like INE.

My memories with INE was good. If I remember it correctly, Brian would go deep in explaining the topic which I really like.

What is the go to video training for CCIE EI these days? I read about kbits.live being great but a bit expensive and little to no trouble shooting. Narbiks is still the guy before taking the lab.

Is anyone here experienced with Cisco Mobility Service (CMX)? Specifically CMX 11 with WLC & Prime Infrastructure. DM Me.

Hi

R1|---10.1.12.0/24---|R2

i created a static route for this subnet on R1

ip route 4.4.4.4 255.255.255.255 10.1.15.5

arp 10.1.15.5 0000.0000.000b ar

this next hop 10.1.15.0 is connected to R1.

R1#show mpls ip binding 4.4.4.4 32

 4.4.4.4/32 

in label:   102    

his local label is advertised to R2 using LDP

R2#show mpls ip binding 

 4.4.4.4/32 

out label:  102    lsr: 1.1.1.1:0

R2)#ip route 4.4.4.4 255.255.255.255 FastEthernet0/0

R2#show mpls ip binding 4.4.4.4 32

 4.4.4.4/32 

in label:   imp-null  

out label:  102    lsr: 1.1.1.1:0

R2#show mpls forwarding-table 4.4.4.4 32

Local   Outgoing  Prefix      Bytes Label  Outgoing  Next Hop   

Label   Label   or Tunnel Id   Switched   interface        

None    No Label  4.4.4.4/32    0       Fa0/0   4.4.4.4   

first of all, why the next hop ip address is 4.4.4.4 ? the next hop ip address for this route is the connected interface which means the next hop should be 10.1.12.2 .

second, why the out label in the LIB on R2 is 102 and the outgoing label in the LFIB is No label? should be both 102 or both No label? where is the symetric? the information are in the LIB should be reflected in the LFIB that is what i know.

Who can help to provide a few suggestion to ccie online video courses for ccie exam?i will study the providers and make a comparison soonthx

I got my CCNP R&S in 2013 and I have been out of loop in regards to the current state of CCIE. I'm planning to try to get my CCIE EI while working full time.

There are 8 CCNP Enterprise specialties. For those studying or already passed the CCIE Enterprise, did you go through all the specialized exams or only a couple that applies to CCIE Enterprise?

I've been asked to do uRPF testing on CGNAt and public SIAs and I'm trying to understand the procedure better. As I understand it, (in strict mode) I am deploying a uRPF configuration on the customer-facing interfaces and making sure they aren't already running a protocol. This testing will also restrict private addresses.

Once I've added the URPF config on the interface, I then can run (install) a Spoof Manager GUI test on that IP (of the customer's interface). Does this sound about right?

I will be attending CiscoLive with my company in February and I'm strongly considering participating in the Sunday seminar: CCIE Enterprise Infrastructure Techtorial [TECCRT-3000].

For those who did attend this session, was it worth it? (both in terms of price and arriving a day earlier).

I imagine it would be similar to the training videos on learningnetwork.cisco.com ?

Please share your experiences and thoughts :)
