Ccnp route / eigrp

Hi guys,

I've just finished EIGRP content and I'm now ready to go to OSPF. Anyway, there are some concepts that i'm not dominating yet (distribute lists using route-maps and IP prefix lists)...

Are these concepts that important?

Thanks in advance.

It's important for the exam, it's important if you want to work in a ccnp level job. You need to know this stuff so you should go over it again until you understand fully.

Absolutely! If you asked me "Is EIGRP important?", I'd say you could go a career without using it, but route-maps matter a great deal. Filtering routes differs a bit by protocol, but these are tools that apply to just about any routing protocol.

Hmm do you guys actually use distribute lists in the real world? i know it's important for the ROUTE test but i have yet to see it in a production network.

We use them at work. One of the secure networks that I work on filters out any routing updates except what is required.

Pain in the butt when we add new services!!!

If your going through the FLG or OCG don't feel overwhelmed just yet on the distribute/prefix list stuff. There is reading in the books that you have yet done which I am sure will clear up a lot of things for you.

Definitely, we use distribute lists all over our network where the routing protocols used are eigrp and bgp. We're dual multihomed and run bgp with 2 isp's so use distribute lists for the ibgp connections and also to filter networks advertised/received from the mpls connections to the other offices.

^^ This. The EIGRP topics covering in those books touch on the topics but the more in depth understanding comes from the chapters that cover route filtering. I don't like how they briefly touch on route filtering in the EIGRP / OSPF sections, I think it should be left completely to its own sections.
