6.11.4 Example for Configuring VRRP6 on an Interface
Networking Requirements
Switch A and Switch B elect a master device according to the configured priorities in a VRRP6
group.
Once the master device is determined in the group, only the master device responds to IPv6
messages. If the master device goes down, the backup device becomes the master device and
the hosts in the private network can still communicate with external networks.
The configured virtual address can be same as the address of any physical interface of the Switch
A or Switch B.
