I agree that you should do filtering on redistribution, period (I prefer the
route-map approach). In the spirit of the KISS principle I always just
spelled out the routes I wanted to block, usually with a prefix list. It is
not as elegant as the proposed solution and requires more commands, but it
sure is a lot easier to troubleshoot - especially at 4:00 when the sweat is
starting to appear on your forehead...

Subject: Mutual Redistribution
Hi,
I'm trying to find a quick and painless way to do filtering on mutual
redistribution points in the lab. Is this filter considered proper?
router ospf 1
redistribute rip subnets metric 100 route-map r2o
router rip
version 2
redistribute ospf 1 metric 2 route-map o2r
route-map r2o deny
match tag 110
route-map r2o permit 20
set tag 120
route-map o2r deny
match tag 120
route-map o2r permit 20
set tag 110
TIA
Guy
