Configuring BFD for static routes

Bidirectional forwarding detection (BFD) provides a general-purpose, standard, medium-, and
protocol-independent fast failure detection mechanism. It can uniformly and quickly detect the
failures of the bidirectional forwarding paths between two routers for protocols, such as routing
protocols and MPLS. For more information about BFD, see High Availability Configuration Guide.

BFD control packet mode

To use BFD control packets for bidirectional detection between two devices, enable BFD control
packet mode on each device for the static route destined to the peer.
To configure a static route and enable BFD control packet mode for it, specify an outgoing interface
and a direct next hop, or specify an indirect next hop and a specific BFD packet source address for
the static route.
To configure a static route with BFD control packet mode enabled (direct next hop):
Step
Enter system view.
