Re: ospf adj problem

a couple of side notes ...
1. unless you use a "neighbour" statement under OSPF process, R3 and R4 will
try to use a link-local multicast, but you don't have "broadcast" keyword in
your map statements...
 2. IMO R5 will not work as reflector for OSPF adj between R3 and R4 (reason
is the same - local-link multicast, TTL=1), those two will never form an adj
in such a topology.

Please correct me if I miss something.

Cheers,
A.
