We will be upgrading our ISP link from a DS3 to an OC3 link. We will be keeping our existing IP addresses and AS number. The new interface already has the same configuration as the exsisting and is currently shutdown. Once I shutdown the DS3 link and bring up the OC3, the BGP should reconverge over the new WAN link, correct? Should the the routing table be cleared with a "clear ip route *"?
I have this problem too.
