Configuring additional VRRP and VRRPE parameters
31
The parameter values are the same as for VRRP.
Router type
A VRRP interface is either an Owner or a Backup for a given VRID. By default, the Owner becomes
the Master following the negotiation. A Backup becomes the Master only if the Master becomes
unavailable.
A VRRPE interface is always a Backup for its VRID. The Backup with the highest VRRP priority
becomes the Master.
This section describes how to specify the interface type, how to change the type for VRRP, and how
to set or change the interface VRRP or VRRPE priority and track priority for the VRID.
NOTE
You can force a VRRP master router to abdicate (give away control) of the VRID to a Backup by
temporarily changing the Master VRRP priority to a value less than the Backup. Refer to “Forcing a
Master router to abdicate to a standby router” on page 1121.
NOTE
The type Owner is not applicable to VRRPE.
NOTE
The IP address(es) you associate with the Owner must be a real IP address (or addresses) on the
interface on which you configure the VRID.
When you configure a Backup router, the router interface on which you are configuring the VRID
must have a real IP address that is in the same subnet as the address associated with the VRID by
the Owner. However, the address cannot be the same.
To configure Router1 as a VRRP VRID Owner, 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)#owner
To configure Router2 as a VRRP Backup for the same VRID, enter the following commands.
Router2(config)#inter e 1/5
Router2(config-if-1/5)#ip vrrp vrid 1
Router2(config-if-1/5-vrid-1)#backup
Router2(config-if-1/5-vrid-1)#advertise backup
To configure a VRRPE interface as a Backup for a VRID and set its VRRPE priority and track priority,
enter commands such as the following.
PowerConnect(config)#inter e 1/1
PowerConnect(config-if-1/1)#ip vrrp-extended vrid 1
PowerConnect(config-if-1/1-vrid-1)#backup priority 50 track-priority 10
Router2(config-if-1/1-vrid-1)#advertise backup
VRRP syntax
Syntax: owner [track-priority <value>]
The track-priority <value> parameter changes the track-port priority for this interface and VRID
from the default (2) to a value from 1 – 254.
