Chapter 7: VRRP Configuration Guide
78 DIGITAL GIGAswitch/Router User Reference Manual
The following table shows the priorities for each virtual router configured on Router R3.
Note:
Since 100 is the default priority, lines 8 and 9, which set the priority to 100, are
actually unnecessary. They are included for illustration purposes only.
Additional Configuration
This section covers settings you can modify in a VRRP configuration, including backup
priority, advertisement interval, pre-empt mode, and authentication key.
Setting the Backup Priority
As described in “Multi-Backup Configuration” on page 74 , you can specify which Backup
router takes over when the Master router goes down by setting the priority for the Backup
routers. To set the priority for a Backup router, enter the following command in Configure
mode:
The priority can be between 1 (lowest) and 254. The default is 100. The priority for the IP
address owner is 255 and cannot be changed.
Setting the Advertisement Interval
The VRRP Master router sends periodic advertisement messages to let the other routers
know that the Master is up and running. By default, advertisement messages are sent once
each second. To change the VRRP advertisement interval, enter the following command in
Configure mode:
Virtual Router Default Priority Configured Priority
VRID=1
– IP address=10.0.0.1/16 100 100 (see line 8)
VRID=2
– IP address=10.0.0.2/16 100 100 (see line 9)
VRID=3
