Re: [OSPF] IETF OSPF YANG and BFD Configuration

Hi Jeff, thank you for the great summary of the discussion, helps me to catch the wave. I'm skeptical that there's realistic scenario where two BFD systems will be requested to run multiple BFD single-hop session between them over the same interfaces (logical or physical). I believe that we should

Re: [OSPF] IETF OSPF YANG and BFD Configuration
