Two or more VRRP backup groups work in load balancing mode. Each router has different
priorities in different VRRP backup groups. Repeatedly configure VRRP priorities to allow
different routers to function as master devices for different VRRP backup groups.
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
interface
interface-type
interface-number
The interface view is displayed.
Step 3
Run:
vrrp vrid
virtual-router-id
priority
priority-value
The VRRP priority value of the router is set.
The default VRRP priority value is 100.
NOTE
l
The priority value 0 is reserved for special use. The priority value 255 is reserved for the IP address
owner. The priority value of the IP address owner cannot be configured. Priority values 1 through 254
can be specified.
l
If devices have the same VRRP priority, the device enters the Master state earlier than others is the
master device. Other devices are backup devices and stop preempting the master state.

4.2.4 (Optional) Configuring VRRP Packet Attributes
VRRP Advertisement packet attributes include the packet sending mode, authentication type,
VRRP version number, TTL detection, and interval at which VRRP Advertisement packets are
sent. Configuring these attributes help improve the performance of a VRRP backup group.
Context
VRRP Advertisement packets are primarily used to determine the status of VRRP backup group
members and elect a master device in a VRRP backup group. After a master device is elected,
the master device sends VRRP Advertisement packets to advertise its VRRP priority and status
to backup devices in the VRRP backup group. A VRRP Advertisement packet contains the
following attributes:
l
VRRP packet sending mode: When a VRRP backup group is configured for a super VLAN
on a device enabled with VLAN aggregation, VRRP Advertisement packets can be sent to
a specified sub-VLAN or all sub-VLANs of the super VLAN. Sending VRRP
Advertisement packets to a specified sub-VLAN efficiently uses network bandwidth.
l
Authentication type: On a secure network, the NE80E/40E forwards all VRRP
Advertisement packets without authenticating them because it considers all VRRP
Advertisement packets valid. On a vulnerable network, the NE80E/40E must authenticate
VRRP Advertisement packets in either simple or Message Digest 5 (MD5) mode.
