I agree. When I do mutual redistribution, I always tag different protocols
with different tags first, check which routes get into ospf database by
"show ip ospf database | begin -5", and create route-map from there. Permit
routes going from the edge into the core, and deny them when they going back
to the edge. I also use "debug ip routing" at the resitribution router, the
command can help to catch route feedback early on.
