1.4.1 Single VRRP Standby Group Configuration Example
I. Network requirements
z Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its
default gateway.
z Switch A and Switch B belong to standby group 1 with the virtual IP address of
202.38.160.111/24.
z If Switch A operates normally, packets sent from Host A to Host B are forwarded
by Switch A; if Switch A fails, packets sent from Host A to Host B are forwarded by
Switch B.
