The above information indicates that if the interface Ethernet 1/1 on Router A is
not available, the priority of Router A reduces to 80 and it becomes the backup.
Router B becomes the master and packets sent from Host A to Host B are
forwarded by Router B.
Network requirements
In the network, some hosts use FE80::10 as their default gateway and some
■
hosts use FE80::20 as their default gateway.
Load sharing and mutual backup between default gateways can be
■
implemented by using VRRP standby groups.
