Specifying an IPv4 VRRP operating mode
A VRRP group can operate in either of the following modes:
• Standard mode—Only the master can forward packets.
• Load balancing mode—All members that have an AVF can forward packets.
After an IPv4 VRRP operating mode is configured on a router, all IPv4 VRRP groups on the router operate
in the specified operating mode.
To specify an IPv4 VRRP operating mode:
Ste

Creating a VRRP group and assigning a virtual IP address
A VRRP group can operate correctly after you create it and assign at least one virtual IP address to it. You
can configure multiple virtual IP addresses for the VRRP group on an interface that connects to multiple
subnets for router backup on different subnets.
Configuration guidelines
• Do not create a VRRP group on the VLAN interface of a super VLAN because network performance
might be adversely affected.
