Gents, I think that the following might be interesting to see regardless from where it came from (ine in this particular case) I want to filter 150.1.3.3 from going to 155.1.146.4 route-map DENYR4 deny 10 match ip address prefix-list R3L0 match ip next-hop prefix-list R4 route-map DENYR4 permit 1000 ip prefix-list R3L0 seq 5 permit 150.1.3.3/32 ip prefix-list R4 seq 5 permit 155.1.146.4/32 router ospf 1 distribute-list route-map DENYR4 in And the route is not filtered... Rack1R6#show ip route 150.1.3.3 Routing entry for 150.1.3.3/32 Known via "ospf 1", distance 110, metric 130, type intra area Redistributing via eigrp 10 Advertised by eigrp 10 metric 100000 1000 255 1 1500 Last update from 155.1.146.1 on FastEthernet0/0.146, 00:09:28 ago Routing Descriptor Blocks: 155.1.146.4, from 150.1.3.3, 00:09:28 ago, via FastEthernet0/0.146 Route metric is 130, traffic share count is 1 * 155.1.146.1, from 150.1.3.3, 00:09:28 ago, via FastEthernet0/0.146 Route metric is 130, traffic share count is 1 Rack1R6# Now if I use standard acces-lists... ip access-list standard R3L0 permit 150.1.3.3 ip access-list standard R4 permit 155.1.146.4 And modify the route-map route-map DENYR4 deny 10 no match ip address prefix-list R3L0 no match ip next-hop prefix-list R4 match ip address R3L0 match ip next-hop R4 It works...
