What routes are you receiving from new provider ? (global, local, customer
etc.)
What routes are you receiving from existing provier ? (same as above)
Are you receiving "default" from any one of the provider ?
or Do you use an over riding default ? (ip route 0.0.0.0 next hop)
When we generally tie up with a customer, who is large size and wants to
receive global + local&customer routes, we have 2 BGP sessions to that
customer, one running from border router (supplying global feed) and the
other from core router (supplying local & customer feed).
So is atnt having single peering and supplying all the prefixes over that ??
rgds
