This should help.
1.Create prefix list with
deny and
permits2. Then attache to a
permit route map
3. redistribute with "static route map"
see below
ip prefix-list MyRoutes seq 10 deny 10.10.76.0/24
ip prefix-list MyRoutes seq 20 permit 10.10.77.0/24
ip prefix-list MyRoutes seq 30 permit 10.10.66.0/24
route-map
MyDist2 permit seq 10
match ip address prefix-list MyRoutes
router ospf 1
redistribute static route-map
MyDist2**************output on neighbour*********10.10.76.blocked others are allowed***********

Subject: OSPF Filter static routes
Hello
Is a 8320 (TL.10.06.0110).
I want only certain static routes to be inserted into OSPF for redistribution.
Im fighting a bit with the route-map, prefix-list setup
For testing purpose i have the following static routes
ip route 1.1.1.1/32 192.168.55.55
ip route 10.1.76.0/24 10.0.1.7
ip route 10.1.77.0/24 10.0.1.7 <<< should NOT be distributed via OSPF
I tried with :
ip prefix-list route-prefixes seq 10 deny 10.1.77.0/24
route-map NoDist deny seq 10
match ip address prefix-list route-prefixes
router ospf 1
......
redistribute static route-map NoDist
However with this no static routes are being distributed anymore.
Thanks for your help
Andreas
