 Switch(config)#router ipv6 vrrp 10

 Switch(config-router)#disable

2.5 enable

 Command: enable

 Function: Enable VRRPv3 virtual router.

 Parameters: None.

 Command Mode: VRRPv3 Protocol Mode.

 Default: There is no configuration by default.

 Usage Guide: Start the corresponding virtual router session. Only the interface of the

enabled router (or the layer-three switch) can actually join the backup group. Before

enabling the virtual router, the virtual IPv6 address and interface of VRRPv3 should be

configured.

 Example: Enable the VRRPv3 virtual router whose ID is 10.

 Switch(config)#router ipv6 vrrp 10

 Switch(config-router)#enable

2.6 preempt-mode

 Command: preempt-mode {true | false}

 Function: Configure the preempt mode of VRRPv3.

 Parameters: None.

 Command Mode: VRRPv3 Protocol Mode.

 Default: It is preempt mode by default.

 Usage Guide: If it is needed that a router (or a layer-three switch) with higher priority

can the role of master router, the preempt mode needs to be configured.

 Example: Configure VRRPv3 as non-preempt mode.

 Switch(config-router)# preempt-mode false

2.7 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
