BFD Model, Interface, and Client Support

The following firewall models do not support BFD: PA-800 Series, PA-500, PA-220, PA-200, and VM-50 firewalls. The models that do support BFD support a maximum number of BFD sessions, as listed in the Product Selection tool.
BFD runs on physical Ethernet, Aggregated Ethernet (AE), VLAN, and tunnel interfaces (site-to-site VPN and LSVPN), and on Layer 3 subinterfaces.
Supported BFD clients are:
  • Static routes (IPv4 and IPv6) consisting of a single hop
  • OSPFv2 and OSPFv3 (interface types include broadcast, point-to point, and point-to-multipoint)
  • BGP IPv4 and IPv6 (IBGP, EBGP) consisting of a single hop or multiple hops
  • RIP (single hop)
