Re: [nsp] BGP: PM3 & Cisco 2524

The 7206 is the core BGP speaker. I don't want to risk tearing down the
rest of the network by making the 7206 a RR client. Maybe I'll just do
OSPF between them. I don't understand why that doesn't work. Even though
it is internal, I thought it should still work. What if I give the 2524
a different AS number?!

:that's a feature of ibgp. set the 2524 up as a route-reflector. make the
