R2511-HP MSR Router Series High Availability Command Reference(V5)

When you configure collaboration between Track and BFD, do not configure the virtual IP address of a
VRRP group as the local or remote address of a BFD session.
Associating a track entry with the echo-mode BFD session detects a directly connected link. Before that,
you must configure the source IP address of BFD echo packets.
Examples
# Create track entry 1, which uses BFD to monitor the link between local IP address 192.168.40.2 and
remote IP address 192.168.40.1 by sending BFD echo packets.
