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 202.38.160.111/24 as its
default gateway.
■ Switch A and Switch B belong to standby group 1 with the virtual IP address of
202.38.160.111.
■ 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-interface 3 which
connects to the Internet is not available, packets sent from Host A to Host B are
forwarded by Switch B.
