VRRP Configuration Commands 799
Description
Use the vrrp vrid track command to configure the switch to track the interface.
Use the undo vrrp vrid track command to stop tracking the interface.
VRRP interface track expends the backup function, which thereby can be
implemented not only when the switch fails, but also when the state of a network
interface is Down. The user can use this command to track or stop tracking an
interface or all the interfaces. After the command is configured, the priority of the
switch will be reduced, if the state of the tracked interface goes Down.
Accordingly, some other switch in the virtual router will have the comparatively
highest priority and become the new Master, thereby implementing the backup
function. The IP address owner does not allow the configuration of interface
tracking.
Each virtual router can track up to 8 interfaces.
Example
# Set to track vlan-interface1 on vlan-interface2, and lower the priority of virtual
router 1 on vlan-interface2 by 50 when the state of vlan-interface1 goes Down.
[3Com-vlan-interface2] vrrp vrid 1 track vlan-interface 1 reduced 50
vrrp vrid virtual-ip Syntax

Description
Use the vrrp vrid virtual-ip command to create a virtual router or add a virtual IP
address to an existing virtual router.
Use the undo vrrp vrid virtual-ip command to cancel an existing virtual router or
an address from the virtual router.
You can add up to 16 virtual IP addresses to one virtual router.
If all of the addresses in a virtual router are deleted, the system will delete the
virtual router automatically.
