Parameters

track-entry-number: Specifies the track entry ID in the range of 1 to 1024.

interface interface-type interface-number: Specifies the outgoing interface by its type and number of the BFD echo packets.

remote ip remote-ip-address: Specifies the destination IP address of the BFD echo packets.

local ip local-ip-address: Specifies the source IP address of the BFD echo packets.

delay: Specifies the delay before the Track module notifies the application modules of the track entry state change. If you do not specify this keyword, the Track module notifies the application modules immediately when the track entry state changes.

negative negative-time: Specifies the delay before the Track module notifies the application modules that the track entry state has changed to Negative. The negative-time argument represents the notification delay in the range of 1 to 300 seconds.

Usage guidelines

After a track entry is created, you can only use the track bfd delay command to modify its notification delay settings. If you execute the track bfd delay command multiple times, the most recent configuration takes effect.

To modify other settings for the track entry, execute the undo track command to remove the track entry, and then execute the track bfd command again.

When you associate Track with BFD, the virtual IP address of a VRRP group cannot be the local or remote address of a BFD session.

Examples

# Associate track entry 1 with BFD to monitor the link between local IP address 1.1.1.2 and remote IP address 1.1.1.1 by sending BFD echo packets through VLAN-interface 2.

positive positive-time: Specifies the delay before the Track module notifies the application modules that the track entry state has changed to Positive. The positive-time argument represents the notification delay in the range of 1 to 300 seconds.

Usage guidelines

After a track entry is created, you can only use the track ip route reachability delay command to modify its notification delay settings. If you execute the track ip route reachability delay command multiple times, the most recent configuration takes effect.

To modify other settings for the track entry, execute the undo track command to remove the track entry, and then execute the track ip route reachability command again.

Route management does not immediately notify the Track module of the route status changes when the following conditions are met:

·     An active/standby device switchover or a RIB process switchover has occurred.

·     The status of the monitored route entry is changed before the routing protocol completes the graceful restart.

You can resolve the problem by configuring the nonstop routing feature.
