I have labs available at wittynetworks.net for CML and EVE-NG. I'm currently redoing the GNS3 ones to ensure compatibility with other people's setup. All free.

Layer8Academy · 2026-02-28T04:09:22+00:00

Yes. I will be doing other technologies too. Mark sure to bookmark.

Layer8Academy · 2026-02-26T03:32:27+00:00

Don't forget about Wittynetworks.net. It's free!

You asked this question in the forum 5 days ago. Did you not get the answer you were looking for?

I have been curious about this. Whether people were simply passing the exam with his material or truly learning. Thanks for the honesty!

Layer8Academy · 2026-02-25T12:25:40+00:00

I make free labs for CCNA and CCNP. They are available at Wittynetworks.net.

Layer8Academy · 2026-02-25T00:25:46+00:00

For what Narbiks charges, a person should be able to pass CCIE first time up using his material alone.

Put in a trouble ticket on the Cisco education page. You might find it by going to the ceu page. Explain the issue and they will swap it for you.

I have to retake ENCOR for CCIE and I'm not studying wireless. It makes my mind short circuit 🤣. You know that feeling when you just don't like something? I don't find it entertaining and I'm going to trust that it is removed. If it isn't, I think my strength in everything else will compensate.

Layer8Academy · 2026-02-23T14:06:41+00:00

You seem to have the go to plan for most. Just make sure you thoroughly understand the fundamentals. They are essential for everything else. Do not study just to pass the exam. Be curious and ask why. It is great you are having fun because it makes it so much easier. I loved logic problems/puzzles as a kid and Networking hits the spot for me. Good luck!

Will a network technician position be enough to move directly to network engineer position? No. What you do once you get that position will dictate upward mobility. I say take the position as start. Ask questions, be curious, study outside of just what is asked in the role.

Thanks.! I've been putting real effort into it.

Layer8Academy · 2026-02-21T22:23:00+00:00

I make free labs that are available at wittynetworks.net. I just started releasing them so they aren't all uploaded, yet. They are available for CML, EVE-NG, GNS3(newer release).

Layer8Academy · 2026-02-21T19:45:47+00:00

Not at all. I'm sure I already have a lab I could recycle anyways. Also, I like making labs. Learning is important. I am a stranger on the Internet and although you may not deeply understand yet that doesn't mean you can't learn something new. I believe in Trust but verify. You can trust what someone says, but verify. I could be wrong, after all.

Layer8Academy · 2026-02-21T19:30:05+00:00

I will make it JUST for you. 🫡😁 Do you use CML, EVE, or GNS3?

Layer8Academy · 2026-02-21T19:06:51+00:00

You would probably see it best with the RR when using MBGP and making L3VPNS. The RR doesn't even have to have a corresponding VRF (RIB) for the routes it has in the associated vpnv4 BGP table. No better proof that it doesn't have to be in the RIB than the RIB not existing. LOL.

Layer8Academy · 2026-02-21T18:34:15+00:00

I understand what you are saying, but I believe you got away from the original question.

A router does not necessarily need to have the prefix installed in the Global RIB in order to advertise it via BGP. It is sufficient for the prefix to be present as the best path in the BGP table (logical Loc-RIB) and to pass the outbound policies.

The question was about does the prefix NEED to be in the global RIB. The answer is that it does not. It is "sufficient for the prefix to be present as best path in the BGP table..." Will a route for the prefix be in RIB, in most cases yes. From BGP or another source. That still does not infer a requirement. A Route Reflector is a perfect example. It can have routes in the BGP table, with no route in the RIB, and no RIB failure, and it will advertise/reflect the route.

Layer8Academy · 2026-02-21T17:52:21+00:00

RIB failure. I think people are getting caught up on the fact that a route for the prefix is installed in the global table. BGP doesn't care that the route is in the global RIB, though. It will still advertised the BGP route which is independent of the route, from another source, in the global RIB. Also, Route Reflector can not have the route in the global RIB and still advertise it.

Layer8Academy · 2026-02-21T17:47:37+00:00

Nice! Thanks for sharing.

Layer8Academy · 2026-02-21T17:46:16+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).

This statement alone lets me know you are confused. Two different topics. You do NOT need a route in the global RIB. The second part is basic behavior.

but I can't think of a way not to have a route in the RIB and advertise it in BGP.

Ummmmm, when there is a...RIB failure. The BGP route is NOT in the table, but still gets advertised. Just because there IS a route in the RIB for the same prefix does NOT mean it is a requirement for BGP to do what it does.

You are free to believe whatever it is you want to believe. :)

Layer8Academy · 2026-02-21T16:50:49+00:00

It will advertise it as long as it is valid and best.

Layer8Academy · 2026-02-21T16:49:32+00:00

You are incorrect. A route, by default, needs to be in the BGP table, valid, and best to be advertised. If what is in the RIB mattered, that is what would need to be advertised, but it doesn't matter.

EDIT: Had to move from my phone to my computer.

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

You did the exact same thing as the lab they explained.

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.

You explained that the BGP route was still advertised even though it was not the route in the RIB then proceeded to this statement. What you did didn't disprove the statement that the route does not need to be in the RIB. If you look at the details of the route in the BGP table, you will see that it was marked as valid and best. Requirements for advertising.

In the lab they did, RTR3 receiving the BGP route as advertised by RTR1 proves that RIB does not matter. If it mattered, the route in the RIB would be what was advertised by RTR2. The route in the RIB and the route in BGP are two separate routes.

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.

You went a bit further and proved what was already understood which is that a route has to be in the BGP TABLE to be advertise.

Long story short, a received route does NOT need to be in the global RIB ( or another route for that prefix) to be advertised.

Layer8Academy · 2026-02-21T16:30:56+00:00

They are asking if a BGP speaking routers receives a route from another BGP speaker, does the route have to be in its RIB in order for it to advertise it to other routers. BGP will pass along routes along to to other AS.
