3Com Switch 8800 Advanced Software V5 Configuration Guide

IPv6-Based VRRP Configuration Example 789
Admin Status : UP State : Master
Config Pri : 100 Run Pri : 100
Preempt Mode : YES Delay Time : 5
Auth Type : SIMPLE TEXT Key : hello
Virtual IP : FE80::10
Virtual MAC : 0000-5e00-0201
Master IP : FE80::2
The above information indicates that if Vlan-interface3 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.
