IPv4 Standby Information:
Run Mode : Standard
Run Method : Virtual MAC
Total number of virtual routers : 1
Interface Ten-GigabitEthernet0/0.2
VRID : 1 Adver Timer : 5
Admin Status : Up State : Master
Config Pri : 100 Running Pri : 100
Preempt Mode : Yes Delay Time : 5

Virtual IP : 202.38.160.111
Virtual MAC : 0000-5e00-0101
Master IP : 202.38.160.2
The output shows that if interface Ten-GigabitEthernet 0/0.1 on LB A is not available, the priority of LB A
is reduced 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
1. Network requirements
• I n t h e s e g m e n t 2 02 . 3 8 .16 0 . 0 / 24 , s o m e h o s t s u s e 2 0 2 . 38 .16 0 .111/24 as their default gateway and
some hosts use 202.38.160.112/24 as their default gateway.
• Load sharing and mutual backup between default gateways can be implemented by using VRRP
groups.
