interface interface-type interface-number: Specifies the outgoing interface for BFD echo packets.
interface-type interface-number represents the interface type and interface number.
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 specified 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. negative-time represents the delay time, ranging
from 1 to 300, in 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. positive-time represents the delay time, ranging from 1 to
300, in seconds.
Description
Use track bfd echo to create a track entry, associate it with the BFD session, specify to use 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.
By default, no track entry that is associated with a BFD session is created.
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 echo delay command. To modify other settings of this track entry,
first delete the entire track entry, and then create a new track entry.
When configuring 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.
