Setting the Device Priority in a VRRP6 Group

Procedure

1. Run system-view

   The system view is displayed.

2. Run interface interface-type interface-number

   The interface view is displayed.

3. (Optional) On an Ethernet interface, run undo portswitch

   The interface is switched to Layer 3 mode.

   By default, an Ethernet interface works in Layer 2 mode.

   

   Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.

4. Run vrrp6 vrid virtual-router-id priority priority-value

   The device priority in a VRRP6 group is set.

   By default, the device priority is 100.

   • Priority 0 is reserved in the system. Priority 255 is reserved for the IP address owner. The configurable priority ranges from 1 to 254.

   • The priority of an IP address owner is fixed at 255 and cannot be manually changed. You can run the vrrp6 vrid virtual-router-id priority priority-value command to change the priority of an IP address owner, but the configured priority does not take effect. If a VRRP device is no longer an IP address owner, the configured priority is used.

   • In a VRRP6 group, if devices have the same priority and attempt to become the master simultaneously, the device where the interface with the largest IP address resides becomes the master. The device that first enters the Master state becomes the master, and other backups remain unchanged.
