Specifying an IPv6 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 the IPv6 VRRP operating mode is specified on a router, all IPv6 VRRP groups on the router operate
in the specified operating mode.
To specify an IPv6 VRRP operating mode:

2. Specify an IPv6 VRRP
operating mode.
• Specify the standard mode:
undo vrrp ipv6 mode
• Specify the load balancing
mode:
vrrp ipv6 mode load-balance
By default, VRRP operates in
standard mode.
Creating a VRRP group and assigning a virtual IPv6 address
A VRRP group can work correctly after you create it and assign at least one virtual IPv6 address for it. You
can configure multiple virtual IPv6 addresses for the VRRP group on an interface that connects to multiple
subnets for router backup.
Configuration guidelines
• Do not create VRRP groups in the VLAN interface of a super VLAN. Otherwise, network
performance might be adversely affected.
• If a router is the IP address owner in a VRRP group, do not configure the ospfv3 area command on
the interface to use the IPv6 address of the interface or the virtual IPv6 address of the VRRP group,
to establish an OSPFv3 neighbor relationship with the adjacent router. For more information about
the ospfv3 area command, see Layer 3—IP Routing Command Reference.
