BFD sessions over AF interfaces for Junos node slicing

Use this feature to configure BFD for BGP, IS-IS, and OSPF over an Abstract Fabric (AF) interface for Junos node slicing. You can use AF interfaces to connect peer guest network functions (GNFs). BFD provides quick failure detection to help achieve fast convergence over GNFs. You can verify BFD sessions on AF interfaces by using the show bfd session command.
