Associating Track with BFD
BFD supports the control packet mode and echo packet mode. A track entry can only be associated with
the echo-mode BFD session, and cannot be associated with the control-mode BFD session. For more
information about BFD, see "Configuring BFD."
BFD f
u
nctions as follows when it is associated with a track entry:
• If the BFD detects that the link fails, it informs the track entry of the link failure. The Track module sets
the track entry to Negative state.
• If the BFD detects that the link is operating correctly, the Track module sets the track entry to Positive
state.
Before you associate Track with BFD, configure the source IP address of BFD echo packets. For more
information, see "Configuring BFD."

Associating Track with CFD
CFD functions as follows when it is associated with a track entry:
• If the CFD detects that the link fails, it informs the track entry of the link failure. The Track module
then sets the track entry to Negative state.
• If the CFD detects that the link is operating correctly, the Track module sets the track entry to Positive
state.
Before you associate Track with CFD, enable CFD and create a MEP. For more information, see
"Configuring CFD."
