61.7 priority
Command:
priority <value>
Function:
Configure the priority of VRRPv3.
Parameters:
<value> is the priority, whose range is from 1 to 254.
Command Mode:
VRRPv3 Protocol Mode.
Default:
Backup routers (or layer-three switches) all have a priority of 100, the priority of IP address owners
are all 255 in the backup group they belong to.
Usage Guide:
Priority decides the state of a router (or a layer-three Ethernet switch) in a backup group. The higher
the priority is, the more possible the router can be a Master. The configurable priority ranges from 1
to 254, while the priority of 255 is reserved to the IP address owner. The priority of 0 has special
usage, which is when disabling a VRRP session, Master will send an advertisement message with a
priority of 0. When Backup receives such advertisement message, it will start a new round of Master
selection. When there are two or more routers (or layer-three switches) in one backup group have
the same priority, the router with biggest local link IPv6 address has higher priority.
Example:
Configure the priority of VRRPv3 as 150.
Switch(config-router)# priority 150
