6.3.3 Configuring Priorities for Interfaces Where a Backup Group
Is Created
Configuring priorities for interfaces on which a VRRP backup group is created allows the VRRP
status on an interface to become Master. The master device forwards network traffic.
Context
In master/backup mode, only one backup group is created. switchs have different priorities in
this backup group. The switch with the highest priority serves as the master and other switchs
are backups.
In load balancing mode, two backup groups or more are created. Every switch has different
priorities in different backup groups. Every switch plays a role based on its priority in a specific
backup group. Different priorities are set for every switch to allow that the masters of VRRP
backup groups are distributed on different switchs.
Do as follows on the interface of each switch in each backup group:
Perform the following step as required to configure VRRP for IPv4 (VRPv4) or VRRP for IPv6
(VRRPv6).

For VRRP for IPv4, run the following commands:
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The VLANIF interface view is displayed.
3. Run:
vrrp vrid virtual-router-id priority priority-value
The priority of the switch in a VRRP backup group is configured.
By default, the priority is 100. Priority 0 is reserved for special purpose. Priority 255
is reserved for the IP address owner and this priority cannot be configured. A priority
ranges from 1 to 254.
For VRRP for IPv6, run the following commands:
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The VLANIF interface view is displayed.
3. Run:
vrrp6 vrid virtual-router-id priority priority-value
The priority of the switch in a VRRPv6 backup group is configured.
