I am fixing to peer with a 3rd carrier, and was hoping to get some design suggestions.
Currently, I do BGP load-sharing across an OC-12 and a Gig-E link. I weight all recieved routes from both eBGP peers to help equalize my outbound traffic down each connection.
I will be peering with a 3rd peer via another Gig-E link, and am only wanting to use my OC-12 for inbound and outbound traffic, if both of my Gig-E links fail.
This is what I was thinking, and please correct me if I am wrong:
I planned on load-sharing my two Gig-E links and weighting my recived routes from these 2 peers higher than the routes recieved over my OC-12, which should control outbound traffic and only use the OC-12 as a last resort. As far as inbound traffic over the OC-12, I was going to poison my routes via BGP prepending towards that peer.
Anyhow, any suggestions would be greatly appreciated! Thanks!
