Switch B becomes the master andpackets sent from Host A to Host B are forwarded by Switch B.Multiple VRRP group configuration exampleNetwork requirements• Hosts in VLAN 2 use 1::10/64 as their default gateway and hosts in VLAN 3 use 2::10/64as their default gateway.• Switch A and Switch B belong to both VRRP group 1 and VRRP group 2. The virtual IPv6addresses of VRRP group 1 are 1::10/64 and FE80::10, and those of VRRP group 2 are2::10/64 and FE90::10.• In VRRP group 1, Switch A has a higher priority than Switch B. In VRRP group 2, Switch Bhas a higher priority than Switch A. In this case, hosts in VLAN 1 and VLAN cancommunicate with the outside through Switch A and Switch B respectively, and if Switch Aor Switch B fails, the hosts can use the other switch to communicate with the outside, so as toavoid communication interruption.
