Hey gang,
I have a question on maximum-paths in BGP;
This is the scenario: 4 T1's running EBGP to our ISP in a multihome peer
session; each of the circuits go to a different POP. Each of the peer
sessions receive a partial routing table from our provider. What we have
found is that load sharing (outbound to our ISP) is virtually non-existant.
well, i'm studying for BCSN and came across the maximum path feature, and it
seems like the solution.
My question is this: we have enabled maximum-path 4 to load share between
the four sessions. This, however has had a neglible effect. Does the fact
that we still hear routes from the provider from different pops affect this?
In other words, since the 4 pops are in a different geographical area, and
therefore may send a different bgp table which in turns overrides the
maximum path command.
I want to try having the provider send a default route instead; the thought
being that our router will not have to decide on best paths, and leave that
to ISP router, but the powers to be don't want that (for some reason...)
Does anyone have any suggestions?
thanks all,
moe
