Re: Distribute Lists vs. Route Maps

The general rule is that you use distribute-list for Distance-vector
protocols (RIP, IGRP)
and Route-maps for link state (OSPF, ISIS).

I learned a lot about these trying to filter rip updates being sent into
OSPF. You should do this. I have configs and a Visio drawing if you want
to see them. It basically relates to blocking a specific RIP subnet from
being advertised into OSPF. Trying this first with Distribute-list, an
second with route-maps is a great learning experience.
