Bfd Echo Packet Mode; Configuring Static Route Frr - HPE FlexNetwork HSR6800 Configuration Manual

Step
Configure a static
2.
route and enable
BFD control packet
mode for it.

BFD echo packet mode

With BFD echo packet mode enabled for a static route, the outgoing interface sends BFD echo
packets to the destination device, which loops the packets back to test the link reachability.
IMPORTANT:
• Enabling BFD for a flapping route could worsen the situation.
• Do not use BFD for a static route with the outgoing interface in spoofing state.
To configure BFD echo packet mode for static routes:
Step
Enter system view.
1.
Configure the
2.
source address of
echo packets.
Enable BFD echo
3.
packet mode for
static routes.

Configuring static route FRR

A link or router failure on a path can cause packet loss and even routing loop. Static route fast reroute
(FRR) enables fast rerouting to minimize the impact of link or node failures.
