Through acquisition, we have acquired another comapony with a different carriers MPLS network. On my native network we run bgp as the routing protocol accross carrier a's MPLS network. The acquired network organizations network is based on OSPF with another carrier. I have orderd a link to the second MPLS network and will terminate that the head end router we use at our main site. My question is do I need ot redistribute the OSPF into BGP to announce all routes between the networks, or could that router stand alone as the default gateway between the two networks without any major instabilities.
I have this problem too.
