Re: Multiple OSPF processes having same router-id ?

Thanks James,

I am struck in a design case where in i have to use a temporary hair-pin to
provide ethernet to MLPPP Bundle L3 connectivity, challenge is MLPPP bundle
cannot go into VRF and that is limitation. i am ending up in a scenario
where i should peer with my own router one from instance and other
interface from global and form OSPF. Knowing that it is not feasible with
same router-id, Just wanted to check what is the practice you guys follow
in production networks, to assign a Global Management ID for all the
instances ospf for easier identification which is obvious or is there any
catch to this logic.

Thanks
