RIP Justification

I am with Scott on this one.. I took the initial question as a focus on the edge... not the CORE. RIP is perfect for the edge to commercial CPEs. Why would want to run OSPF/ISIS at the edge. I would hope that it would be common practice to not use RIP in the CORE....


Why would you run dynamic to simple CPE at all?

Static route that stuff through DHCP or RADIUS and move on.

If you need dynamic routing across administrative boundaries, that's not a good place
for RIP, that's a good place for BGP.
