The above information indicates that in VRRP group 1, Device A is the master, Device B is the backup and
the host with the default gateway of 1::10/64 accesses the Internet through Device A; in VRRP group 2,
Device A is the backup, Device B is the master and the host with the default gateway of 1::20/64
accesses the Internet through Device B.
NOTE:
Multiple VRRP groups are commonly used in actual networking. In IPv6 network, to share load among
multiple VRRP groups, manually configure the default gateway for hosts.
VRRP Load Balancing Mode Configuration Example
Network requirements
• Device A, Device B, and Device C belong to VRRP group 1 with the virtual IPv6 address of
FE80::10.
• Hosts on network segment 1::/64 use FE80::10 as their default gateway. Use the VRRP group to
ensure that when a gateway (Device A, Device B, or Device C) fails, the hosts on the LAN can
access the external network through another gateway.
• VRRP group 1 works in load balancing mode to make good use of network resources.
