Hi I have asked this question on the forums but got no reply I want to run BFD and OSPF together. I have a few routers that have multiple legs of OSPF, but I can't run BFD on some legs, because I have some legacy cisco equipment that doesn't do BFD (ASA5520 8.5). Can I limit BFD to specific legs of OSPF determined network interface Can I limit BFD support on BGP by specific peers even if I have multiple peers on the same interface, last one can I have multiple BGP + BFD peers on the same interface ???

Hi Alex, BFD will only become active after a BGP or OSPF "session" is successfully established. With BGP it is configured per-peer. With OSPF it is configured per-interface. If you are running point-to-point links e.g. only two devices talking OSPF then just turn it on for those "interfaces". If you have multiple neighbours on an interface, BFD will only work to the other neighbours that have it configured. I hope that answers your question.

Hi Did some more reading, think I am happy with the BGP side of things. The ospf is where I am more worried. I have a vlan my backbone that has 9 OSPF routers all ROS and 1 cisco There cisco doesn't do BFD. I would like to turn on BFD, but I want to turn it off for the cisco node.. Am I just going to end up with my ROS boxes flapping because the cisco isn't sending BFD ?? A

Get a decent IOS for the cisco, then it should do BFD.
