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
Multiprotocol Label Switching (MPLS). For more information about BFD, see High Availability
Configuration Guide.
BFD control mode
To use BFD bidirectional control detection between two devices, enable BFD control mode for each
device's static route destined to the peer.
To configure a static route and enable BFD control mode for it, specify an output 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 BFD control mode for a static route (direct next hop):
