Hello. Redistribute ospf xx subnets has some unusual behavior compared to other redistribution mechanisms. Instead of dumping everything from ospf into the other routing protocol, it only does a subset of routes. (If I remember right, only "internal" routes.)
I think the command you probably want is... Redistribute ospf 123 match internal external 1 external 2 Also, if you have nssa's, you may have to tack nssa-external on the end of that. Good luck, Ejay P.s. Unidrectional redistribution good.
