Core Routing Protocol

Core Routing Protocol

Core Routing Protocol

(OP)
I've been studying for BSCI and been practicing routing protocols in GNS3. Im currently building a core network and would want your opinion on what routing protocol to use.

Initially, i was thinking of using ibgp and would would use eigrp for igp. Basically i have 4 core routers (WAN) interconnected via gigabit ethernet.

I decided to use bgp because this is what we used on our core network at work. Any suggestions would really be appreciated.

Thanks.

RE: Core Routing Protocol

If it were me, I'd run through setting up all of the routing protocols as your IGP.  Would give best practice in seeing them all in action as well as how to configure them.  I'd even have them all configured at the same time to play with adjusting AD values and watching the protocols adjust to the changes.

But that's just me.

That's a good idea. I;ll try that one :)

RE: Core Routing Protocol

I agree with lerdalt on configuring all the IGPs first and understanding them individually, then play with two IGPs in different parts of the network and redistribute between them with and without filters. Also, play with injecting default routes. After that, set up EBGP and IBGP and see their behaviors individually. Try to make your BGP act as your IGP and see the issues there. Then, put BGP/IGPs together to get the big picture of how they interact. You will have many hours of fun!

RE: Core Routing Protocol

I remember going through the same sort of lab when working on the BSCI.  I think that was probably the most fun I actually had while doing any of the studies.  Just have 3 to 4 routers at my finger tips and a white board.  Would draw up how I wanted everything to connect, then put the configuration together.

Was great to see feasible successors for EIGRP, and just watch the whole routing topology change with just a few tweaks.
