# When interface GigabitEthernet 1/0/1 on Router A fails, display the detailed information
about VRRP group 1 on Router B.

The output shows that when interface GigabitEthernet 1/0/1 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.
Multiple VRRP groups configuration example
Network requirements
 In the network, some hosts use 1::10/64 as their default gateway and some hosts use 1::20/64
as their default gateway.
 Load sharing and mutual backup between default gateways can be implemented by using VRRP
groups.
