Often it depends on what your layout looks like and what
your current IGP databases look like. When you redistribute between
protocols, in order for a route to pass through redistribution, it has to be the
best path in the RIB of the protocol it's coming from AND it has to be in the
routing table from that RIB. If you have an interface that has been added
into OSPF on a router, when you look at "show ip route" it will be seen as
connected. Therefore that particular link/network will not be
redistributed into EIGRP or RIP or whatever you're running.
So "redistribute connected" is often needed to fix
this. This is discovered through some quick verifications on different
routers to assure that all routes as seen as expected.

Subject: [OSL | CCIE_RS] Rdistribute connected
Hi
I have a question which is very critical to me as i really need to
understand. Why in every routing protocol, the redistribute connected is done
with all of the subnets connected? Although some of this subnets is advertised
through other routng protocol on the same router. Is there a technical
obligation for this? or does it help in other kinds of redistribution?
I feel that there is something hidden in this issue?
Thanks/Regards
