Hello, I'm trying to implement CARP on our edge BGP OpenBSD routers. CARP itself seems to be working perfectly but I'm having problems figuring out how to propertly configure BGP.
I have couple of external IP's on my network, so limited number of them is not an issue (as it's often with internet exchange points). >From claudio's presentation it seems to me doing it by "depend on carp0" is wrong [1]. My setup is like this: [ upstream ] 10.1.1.254 | 10.1.1.1 10.1.1.2 ---- carp0 ---- 10.1.1.3 [ router#1 ] [ router#2 ] Should I peer both routers using their external IP's to my upstream ISP and keep IBGP session between both of them? Or should I use "depend on carp0" and "local-address 10.1.1.1" on both of them? In this case, what am I supposed to announce between both of my routers? Thanks, Peter 1. http://www.openbsd.org/papers/linuxtag06-network/mgp00028.html
