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 ???
