3Com Switch 8800 Advanced Software V5 Configuration Guide

786 CHAPTER 54: VRRP CONFIGURATION
The above information indicates that if Switch A fails, Switch B becomes the
master, and packets sent from Host A to Host B are forwarded by Switch B.
VRRP Interface Tracking
Configuration Example
Network requirements
■ Host A needs to access Host B on the Internet, using FE80::10 as its default
gateway.
■ Switch A and Switch B belong to standby group 1 with the virtual IP address of
FE80::10.
■ If Switch A operates normally, packets sent from Host A to Host B are
forwarded by Switch A; if Switch A is in work, but its Vlan-interface3 which
connects to the Internet is not available, packets sent from Host A to Host B are
forwarded by Switch B.
