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
