Hi,
Thanks to everyone that replied to my post on failover configuration. This has lead me to this post. I'm at a point now where I'm looking at dual-homing with two BGP peers upstream. Now what I am looking at doing is as follows:
BGP Peer with Provider A who is multihomed to other providers. BGP Peer with Provider B who is not peered with provider A
I have an existing relationship with provider A, colo, cross connects etc. Provider A has offered to get the PI space, ASN number, purchase the transit for us with provider B and manage cross connects to provider B (they say they have a diverse "fibre backhaul network"). This is quite attractive from a support and billing perspective. Also suspect that provider A will be able to get more attractive pricing from Provider B than I would be able to.
Am I missing things that I need to consider?
Don't let them cross connect over their network. Bring it in to your site separate from A, otherwise there's no point in the multihoming exercise. ~Seth
