Please find attached diagram.
Currently all 4507 as shown on the diagram have OSPF configured and ip default route pointing to Corporate border router. That said all 4507's are configured with 'default-information originate metric type 1'.
I will setup BGP and get rid of the static route on 4507's.
Proposal is to have only (1) 4507 per site peering eBGP with corporate border router, for simplicity reasons.
My question is:
In this case, should I remove the 'default-information originate metric 1' entry for the 4507's which will not peer eBGP? My point is, since 4507A and 4507C are not peering with Corporate router, they will not know how to send traffic out, correct?
If you have suggestions on how to handle this scenario please let me know.
