Until today i had the following... Two border routers(7206VXR) connected to
a 3750 Stack. the borders do ibgp with each other and the borders and
3750's do OSPF. Here's a quick text network design i created.

Today i brang on a new provider, since most of my traffic is directed out
border1 and decided to add the provider to border2. Now i'm not sure if
things are working right. If i do a `sh ip bgp 72.14.207.99` on border1 i
see two paths. one path is out ProviderC on border2 and the other path is
out ProviderA on border1.
Now if i do the same thing on border2 i see 3 paths availible. One out
providerC on border2, one out providerB on border2, and other out providerB
on border2. All three of these paths are out border2... what happened to
the paths out border1?
I'm not sure if maybe i have my ibgp configured wrong. If i do a sh ip bgp
sum on border2 i see the border1 session but it only shows 71033 prefix's.
If i do the same on border1 i see the border2 session and it shows 244993
prefix's.
Anybody give me a idea about what may be happening here... My understanding
here is that if a packet comes into border1 and the better exit provider is
connected to border2 that border1 should send it to border2 and then out the
provider and vis verse.
