Configuration prerequisites
Before configuring track-BFD collaboration, configure the source address of the BFD echo packets.
Refer to BFD Configuration in the High Availability Configuration Guide for details.
Follow these steps to configure Track-BFD collaboration:
To do… Use the command… Remarks
Enter system view system-view —
Create a track entry, associate it
with the BFD session, and specify
the delay time for the track module
to notify the application modules
when the track entry status
changes
track track-entry-number bfd
echo interface interface-type
interface-number remote ip
remote-ip local ip local-ip [ delay
{ negative negative-time |
positive positive-time } * ]
Required
No track entry that is associated
with the BFD session is created by
default.
When configuring collaboration between track and BFD, do not configure the local address or remote
address of a BFD session as the virtual IP address of a VRRP group.
Configuring Collaboration Between the Track Module and the Interface Management
Module
Through the following configuration, you can establish the collaboration between the track module and
the interface management module, which informs the track module of the changes of the physical
status and Layer 3 protocol status of an interface.
Follow these steps to configure collaboration between the track module and the interface
management module:
To do… Use the command… Remarks
Enter system view system-view —
Create a track entry, associate it
with the interface management
module to monitor the physical
status of an interface, and specify
the delay time for the track module
to notify the application modules
when the track entry status
changes
track track-entry-number
interface interface-type
interface-number [ delay
{ negative negative-time |
positive positive-time } * ]
Required
Use either approach
No track entry that is associated
with the BFD session is created by
default.
