I have something like the following:
R <-> R
I run BGP with my ISP on the router on the right. The router on the left is a new router that I'm installing and it's going to be peering with another router that I have over a MAN. I need to have the fastest convergence possible. I was going to configure iBGP between the 2 routers. Currently, my switch is running eBGP because that's just the way that it was set up in the past. I wanted to change this to be in the same AS as my routers or COMPLETELY change the routing protocol to OSPF. What's recommended? In GNS, iBGP converges slow. This could be different in the real world, but I'm thinking that OSPF would be faster. Any suggestions?
