Trying to setup eBGP with two providers. I would like to use one for primary internet access and the other one to primarily only reach networks part of the second peer. For example only access Comcast users using Comcast peering.
So peer A internet in and out
peer B only their network
if peer A fails use peer b for both b's network and internet and vise versa with peer B.
Here is my question. If peer B and A are also peering with let's say peer G (exp google), how can we make peer G use peer A instead of peer B? G will have the same number of AS to reach the us. Is there a way to influence the routing decisions through bgp of not only my peers but their peers also?
hope that made sense :)
