By default, adver-interval is configured to be 1.
VRRP interface track function has expanded the backup function. Backup is
provided not only to the interface where the virtual router resides, but also to
some other malfunctioning switch interface. By implementing the following
command you can track some interface.
If the interface which is tracked is Down, the priority of the switch including the
interface will reduce automatically by the value specified by value-reduced, thus
resulting in comparatively higher priorities of other switches within the virtual
router, one of which will turn to Master switch so as to track this interface.
When the IP forwarding module (IFM) device is being monitored, the priority of
the switch including the interface will increase automatically by the value specified
by value-increased. When the interface or the IFM device of this interface is Down,
the priority of the switch will decrease by the value specified by value-reduced,
thus resulting in comparatively higher priorities of other switches within the virtual
router, one of which will turn to Master switch so as to track this interface.
Perform the following configuration in VLAN interface view.
Table 600 Configure switch to track a specified interface
Operation
Configure the switch to track a specified
interface
Stop tracking the specified interface
By default, value-reduced is taken 10 and value-increased is taken 2.
n
When the switch is an IP address owner, its interfaces cannot be tracked.
If the interface tracked is up again, the corresponding priority of the switch,
including the interface, will be restored automatically
You can only track up to eight interfaces in one virtual router.
After the above configuration, execute display command in any view to display
the running of the VRRP configuration, and to verify the configuration. Execute
debugging command in user view to debug VRRP configuration.
