Bidirectional 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, use one of the following methods:
•
Specify an output interface and a direct next hop.
•
Specify an indirect next hop and a BFD packet source address for the static route.
To configure BFD control mode for an IPv6 static route (direct next hop):
Step
1.
Enter system view.
2.
Configure BFD
control mode for an
IPv6 static route.
To configure BFD control mode for an IPv6 static route (indirect next hop):
Step
1.
Enter system view.
2.
Configure BFD
control mode for an
IPv6 static route.
Single-hop echo mode
With BFD echo mode enabled for a static route, the output interface sends BFD echo packets to the
destination device, which loops the packets back to test the link reachability.
IMPORTANT:
Do not use BFD for a static route with the output interface in spoofing state.
To configure BFD echo mode for an IPv6 static route:
Step
1.
Enter system view.
