R1, R2 and R3 are running BGP and OSPF. An OSPF E1 (155.100.5.0) route is
present in their routing table. On R2 I'm redist this E1 into BGP. I only
want this route to go out E0 to AS254. I'm using a dist list to filter it from
going out S0.1 but I can't seem to get it to work as it propagates to R3 and R1
as a BGP route. I've attached the config for R2 and the sh ip route for R2 and
R3.
Looking for ideas...
Thanks,
Bill
