• IPv4—IPv4 protocol status of the monitored Layer 3 interface.
• IPv6—IPv6 protocol status of the monitored Layer 3 interface.
track bfd
Use track bfd to create a track entry, associate it with the BFD session, specify to use control or echo
packets in BFD probes, and specify the delay time for the Track module to notify the application modules
when the status of the track entry changes.
Use undo track to remove the track entry.

track track-entry-number bfd { control | echo } interface interface-type interface-number remote ip
remote-ip local ip local-ip [ delay { negative negative-time | positive positive-time } * ]

Parameters
track-entry-number: Specifies the track entry ID in the range of 1 to 1024.
control: Specifies the control packet mode for the associated BFD session.
echo: Specifies the echo packet mode for the associated BFD session.
interface interface-type interface-number: Specifies an interface by its type and number to save BFD
configurations. In echo packet mode, the interface serves as the outgoing interface for BFD echo packets.
In control packet mode, the interface must be the local end of the BFD session.
remote ip remote-ip: Specifies the destination IP address of the BFD echo packets.
local ip local-ip: Specifies the source IP address of the BFD echo packets.
delay: Specifies that the Track module notifies the application modules of the track entry status change
after a specific delay time. If this keyword is not provided, the Track module notifies the application
modules immediately when the track entry status changes.
negative negative-time: Specifies the delay time for the Track module to notify the application modules
that the status of the track entry changes to Negative. The negative-time argument represents the delay
time in the range of 1 to 300 seconds.
positive positive-time: Specifies the delay time for the Track module to notify the application modules that
the status of the track entry changes to Positive. The positive-time argument represents the delay time in
the range of 1 to 300 seconds.
