This is what CCO says:
Q: Can I use the distribute-list in/out command with
OSPF to filter routes?
A: OSPF routes can't be filtered from entering the
OSPF database. The distribute-list in command only
filters routes from entering the routing table, but it
doesn't prevent link-state packets from being
propagated.
~~~ MY PROBLEM ~~~
Diagram:
R1
|
R2--R3
R1 learns 160.160.0.0/22 from R2, R2 learns this from
R3. Fairly simple right?
I want to put a distribute-list inbound on R2's serial
interface to prevent R1 from learning this
route/network.
Config on R2 here:
distribute-list 108 in Serial1/0
access-list 108 deny ip 160.160.0.0 0.0.3.255 any
Problem:
R1 still has the route in it's routing table!!! Doh!
CCO says it should not be in the routing table, but it
should be in the OSPF database.
Q) Any tips/help/suggestions?
