The above information indicates that in standby group 1 Switch A is the master,
Switch B is the backup and the host with the default gateway of
202.38.160.111/24 accesses the Internet through Switch A; in standby group 2
Switch A is the backup, Switch B is the master and the host with the default
gateway of 202.38.160.112/24 accesses the Internet through Switch B.

Single VRRP Standby
Group 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 IPv6 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 fails, packets sent from Host A to Host B are
forwarded by Switch B.
