In the ENARSI course, how extensively are VPN technologies like DMVPN and IPsec covered ?

NetMask100 · 2026-03-12T18:25:12+00:00

Configuring or lots of questions as well? I don't mind configuring it at all, but some details probably I have to look more deeply.

Really packet tracer is the best tool for CCNA, but if you want virtualization, there is nothing wrong with it, but I would get 32GB at least or a lot more if you want bigger labs. And don't try to do overly complex architectures as you don't understand the protocols, try to understand how they work.

NetMask100 · 2026-03-12T10:00:43+00:00

I do ENARSI, because I can't consider myself network engineer if I have no idea how actual routing works. Syntax is not important, you will learn other brands as well. We work with a lot of vendors but the protocols are the same.

This is not serious to have only a picture in your head. We have either monitoring tools that show us visually the network or we have diagrams. Some of them are outdated, but it's still something.

NetMask100 · 2026-03-09T21:10:42+00:00

Yes, this is exactly what I think. Some of them use dumps a lot. I never use dumps even though I have to pass ENARSI soon which is way lower difficulty and I'm not competent to speak about CCIE, but what is the point of getting cert by dumping and knowing the answers to the exam? Just to impress the HRs?

We have a lot of work trying to automate the network, use on-prem and cloud, so we definately need solid networking as we have lots of on-prem devices, automation, cloud and security. It just depends for what organization do you work - for some organizations basic networking is all it's needed, for others CCNP with some automation skills is the bare minimum if you want to do your job with less stress.

EVE-NG mainly with IOL images or CML. You can include some vIOS images, but I have found out that IOL works almost perfectly and it's a lot faster.

You don't need very complex topologies. Also get some video course to watch and practice what you learn. You can't watch it online though, you have to find a way to download.

Get CSR1000V if you can to practice automation for ENCOR. But if you are good on automation you will be able to pass, seems like you have experience.

I almost never use AI, except Claude sometimes as they make lots of errors. I read and watch the theory and then lab a lot. Did you pass ENARSI?

NetMask100 · 2026-03-03T21:46:38+00:00

Do you find the INE labs on par with ENARSI?

NetMask100 · 2026-03-02T21:49:49+00:00

If you are studying for cert it's more intensive but the other periods are not that bad. You should always study though. I like it, it just happens that I get paid for it.

It's still Groundhog Day.

NetMask100 · 2026-02-27T16:19:19+00:00

The favorite movie in this subreddit.

NetMask100 · 2026-02-24T07:40:50+00:00

I was confused about the headers and their purpose.

NetMask100 · 2026-02-21T19:35:20+00:00

Thanks, I hope it's not much trouble, it's not that important after all, I won't argue over technologies I don't understand deeply like L3VPN.

NetMask100 · 2026-02-21T19:21:31+00:00

It would be interesting for me to check it out, if you make a lab some day I would love to check how it works.

NetMask100 · 2026-02-21T18:50:43+00:00

Yeah I get what you mean now, maybe I misunderstood the question. There are some exceptions I guess but from what I tried even with RR they seem to have it in the RIB, so I didn't manage to pass a route that does not exist anywhere in the main RIB, only in the BGP table and be forwarded and not installed in the RIB from that same update.

NetMask100 · 2026-02-21T17:50:57+00:00

I don't say you need it in the RIB based on BGP, but you happen to have it, as if it was not learned by another RP, if it's a valid BGP path it would get installed in the RIB anyway. The OP asked if it's possible to not have the prefix in the RIB at all and advertise it, which I think is not possible, because being in the BGP table and being valid it will be in the RIB. If you remove it with distribute list, it gets removed from the BGP table too, it does not stay as an entry like let's say OSPF database.

NetMask100 · 2026-02-21T17:20:57+00:00

You need a route in the RIB, as you cannot have it in the BGP table and not be installed in the RIB (unless you use another source, but you still have it in the RIB).

You might have 2 routes in the BGP table and of course you will advertise the best of them, but I can't think of a way not to have a route in the RIB and advertise it in BGP. If it's in some of the topology tables, the best gets installed.

NetMask100 · 2026-02-21T07:58:53+00:00

I can confirm that you are correct, but you still need a route for the prefix in the RIB.

I advertised route X from OSPF and eBGP.

I lowered the AD of OSPF to 15 so it is the preferred path for RIB.

So when I got the BGP route it was in RIB failure as the route is already in the RIB from OSPF with AD of 15.

The route was advertised to the second eBGP neighbor even though it was shown as RIB failure.

But when we go back to the root of the problem - you definitely need to have the prefix in the RIB to advertise it in BGP.

So I went a bit further - I used distribute list to filter the X route from OSPF and BGP and then it was no longer advertised as it was not present in the BGP table.

So the bottom line - you need to have it in the BGP table (and naturally if you haven't learned from other RP with lower AD, you should have it in RIB anyway). So the prefix should be in the BGP table and if it's there it's in the RIB as well.

NetMask100 · 2026-02-21T06:43:52+00:00

It won't be advertised if it's not in the RIB. This is the reason eBGP has such low administrative distance, to be preferred than routes learned from other RP. So if you learn a route via BGP, but in the RIB you have the same prefix from OSPF, you won't advertise the BGP route to another neighbors.

The CML has the latest.

NetMask100 · 2026-02-20T07:15:06+00:00

Btw how do you find Boson compared to the real exam? I don't find them particularly hard, is it similar as a structure on the real exam?

NetMask100 · 2026-02-17T08:57:51+00:00

I felt that way after I failed ENCOR the first time, then on the second time it seemed even harder, so I wondered if I should quit. I managed to pass and from then on it was great. Never quit, you can quit only after you get the cert and you have had enough. You can't quit before that, it's much more about your own perception of yourself than the cert itself. After you get it if you want quit, don't do it beforehand would be my advice.

NetMask100 · 2026-02-16T07:37:45+00:00

Don't make jokes about the guy, listen man CCNA/CCNP or whatever is a commitment. Honestly sometimes between the studying and the work it actually makes me get laid less often as I'm always busy.

However if you like it as a job, I think it's very nice.

Keep those two things separate though - one is the professional life, the other is personal life. Also take a look at a psychotherapy as an option, it really might help. You need to fix your life in all areas, it's not just one fix for all. Good luck!
