The output shows that Switch A is operating as the master in VRRP group 1 to forward Internet
traffic for hosts that use the default gateway 10.1.1.100/25, and Switch B is operating as the
master in VRRP group 2 to forward Internet traffic for hosts that use the default gateway
10.1.1.200/25.
IPv6 VRRP configuration examples
This section provides examples of configuring IPv6 VRRP applications on switches.
Single VRRP group configuration example
This section provides an example of configuring a single VRRP group on switches.
Network requirements
Switch A and Switch B form a VRRP group, and use the virtual IP addresses 1::10/64 and FE80::10 to
provide gateway service for the subnet where Host A resides, as shown in Figure 18 .
Host A learns 1::10/64 as its default gateway from RA messages sent by the switches.
Switch A operates as the master to forward packets from Host A to Host B. When Switch A fails, Switch
B takes over to forward packets for Host A.
