Usage guidelines
After a track entry is created, you cannot change its settings except the delay time. To change the delay
time for this track entry, use the track bfd delay command. To modify other settings of this track entry, first
delete the entire track entry, and then create a new track entry.
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.
Associating a track entry with the control-mode BFD session detects an indirectly connected link. You
must make this configuration for both the local and remote ends. Otherwise, BFD does not take effect.
