Why not just use an incoming distribute list on R3? Create an ACL blocking R1's routes on R3 and then create an inbound distribute list on R3 calling this access list. For example, let's say you have the following loopbacks on R1 that are in OSPF area 0
200.0.0.1 1.1.1.1 11.11.11.11 You could create this on R3 access-list 1 deny 1.1.1.1 access-list 1 deny 11.11.11.11 access-list 1 deny 200.0.0.1 access-list 1 permit any now call it in distribute list router ospf 1 distribute-list 1 in s0/0 Done Thank you.
