Two MPLS networks with different routing protocols

Unanswered Question
Aug 29th, 2007

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.

yes you would have to redistribute.

But make sure you do not end up with the same RFC1918 address which are already in use at your side. If this is the case you need to NAT the address space and redistribute it on your side
