Configuring BFD for static routes
To configure BFD for static routes by using IPv4 and IPv6 addressing, you must first set up the static route between the two peer systems.
If a static route exists between two nodes, BFD must be configured on both nodes. The static route is enabled and made available for use only when BFD is in the up state; otherwise, the static route is inactive. BFD for static routes is available for both single hop and multiple hops.
No keyword exists in the Vyatta CLI to configure BFD multiple-hop sessions, although multiple-hop sessions are supported. A BFD session is set up either in single-hop or multiple-hop mode based on the next-hop reachability from the source system. If the next hop for the destination is directly connected, BFD comes up as a single-hop session, and, if it is recursively reachable, BFD is set up as a multiple-hop session.
