Configuring VRRP

Track Port

You can configure the VRID on an interface to track another interface on the router. This is quite useful for tracking

the state of the exit interface for the path for which the VRID is providing redundancy. See "Track Ports and Track

Priority" on page 8.

USING THE CLI

To configure 1/6 on Router1 to track interface 2/4, enter the following commands:

Router1(config)# inter e 1/6

Router1(config-if-1/6)# ip vrrp vrid 1

Router1(config-if-1/6-vrid-1)# track-port e 2/4

syntax: track-port ethernet <slot/port>|ve

Track Priority

If a tracked interface goes down, VRRP changes the VRRP priority of the router to the track priority, which typically

is lower than the router's VRRP priority and lower than the VRRP priorities on the Backup routers.

Ports and Track Priority" on page 8. The default track priority for the owner of the VRID's IP address(es) is 2. The

default track priority for Backup routers is 1.

You enter the track priority as a parameter with the owner or backup command. See "Configuring a Virtual

Router" on page 11.

syntax: owner [track-priority <value>]

syntax: backup [priority <value>] [track-priority <value>]

Backup Preempt

By default, a Backup VRRP router that has a higher priority than another Backup router that has become Master

can preempt that router to become the new Master router. If you want to prevent this behavior, disable

preemption.

NOTE: Regardless of the setting for the preempt parameter, the owner always becomes the Master again when

it comes back online.

USING THE CLI

To disable preemption on the backup VRRP interface for VRID1 on Router2, enter the following commands:

Router1(config)# inter e 1/6

Router1(config-if-1/6)# ip vrrp vrid 1

Router1(config-if-1/6-vrid-1)# non-preempt-mode

syntax: non-preempt-mode
