Changing the backup priority
When you enter the backup command to configure the device as a VSRP Backup for the VRID, you
also can change the backup priority and the track priority:
•
The backup priority is used for election of the Master. The VSRP Backup with the highest
priority value for the VRID is elected as the Master for that VRID. The default priority is 100. If
two or more Backups are tied with the highest priority, the Backup with the highest IP address
becomes the Master for the VRID.
•
The track priority is used with the track port feature. Refer to
“Changing the default track priority”
To change the backup priority, enter a command such as the following at the configuration level for
the VRID.
BigIron RX(config-vlan-200-vrid-1)# backup priority 75
Syntax: [no] backup [priority <value>] [track-priority <value>]
The priority <value> parameter specifies the VRRP priority for this interface and VRID. You can
specify a value from 3 – 254. The default is 100.
For a description of the track-priority <value> parameter, refer to
Saving the timer values received from the master
