[c-nsp] OSPF Router ID

[Metz, E.T. (Eduard)]

AFAIK the OSPF process ID or domain ID are relevant only in the provider
(MPLS VPN) domain (PE-PE), and even then only for the BGP-OSPF
redistribution. They should not interfere with OSPF adjacencies on CE-PE
links. Do you have any information on the state in which the neighbor
setup gets stuck, or some debug traces of this process?
