# When interface GigabitEthernet 0/1 on LB A fails, display the detailed information about VRRP
group 1 on LB B.
[LBB-GigabitEthernet0/2] display vrrp ipv6 verbose
IPv6 Standby Information:
Run Mode : Standard
Run Method : Virtual MAC
Total number of virtual routers : 1
Interface GigabitEthernet0/2
VRID : 1 Adver Timer : 400

The output shows that when interface GigabitEthernet0/1 on LB A is not available, the priority of
LB A reduces to 80 and it becomes the backup. LB B becomes the master and packets sent from
Host A to Host B are forwarded by LB 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.
