but ospf and bgp are two different routing protocols in context; an IGP and
an EGP.
if two different IGPs are running on the same router, then the "ships
passing in the night" refers to the different IGPs (for example, EIGRP and
OSPF) routing and advertising different networks, which is completely
permissable, and applicable in certain environments (example: post-merger
networking, where shared information is not necessarily required, but shared
network support is required-instead of redistributing back and forth, the
network staff has both connections in the NOC to monitor both). Also,
during a network cut-over, not allowing the old and new addressing schemes
to intermingle requires different routing processes - multiple Autonomous
Systems, or independent routing protocols work in that case.
btw, the 'ships-in-the-night' citation comes from OSI routing (IS-IS) as the
method for configuring two different routable *network* protocols
independently (for example, AppleTalk and IP)
