VRRP Configuration Commands
1-8
priority: Switch priority to be set. This argument ranges from 1 to 254.
Description
Use the vrrp vrid priority command to set the priority of a switch in a backup group.
Use the undo vrrp vrid priority command to revert to the default priority.
By default, the priority of a switch in a backup group is 100.
Switch priority determines the possibility for the switch to become a master switch. A
switch with larger priority is more likely to become a master switch. Note that the priority
of 0 is reserved for special use, and the priority of 255 is for IP address owners. That is,
the priority of a switch that owns a virtual router IP address is fixed to 255 and cannot be
modified.
Examples
# Set the priority to 120 for a switch in the backup group.
