1102 CHAPTER 87: VRRP CONFIGURATION
If Switch A is in work, but its interface VLAN-interface 3 is not available, you can
still ping through Host B on Host A. You can use the display vrrp ipv6 command
to view the detailed information of the standby group.
# If Switch A is in work, but its interface VLAN-interface 3 is not available, the
detailed information of standby group 1 on Switch A is displayed.
[SwitchA-Vlan-interface2] display vrrp ipv6 verbose

[SwitchB-Vlan-interface2] display vrrp ipv6 verbose
IPv6 Standby Information:
Run Method : VIRTUAL-MAC
Virtual IP Ping : Enable
Interface : Vlan-interface2
VRID : 1 Adver. Timer : 500

The above information indicates that if VLAN-interface 3 on Switch A is not
available, the priority of Switch A reduces to 80 and it becomes the backup.
Switch B becomes the master and packets sent from Host A to Host B are
forwarded by Switch B.
Multiple VRRP Standby
Group Configuration
Example
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.
