The above information shows that in VRRP group 1 Switch A is the master, Switch B is the
backup and hosts with the default gateway of 202.38.160.100/25 accesses the Internet through
Switch A; in VRRP group 2 Switch A is the backup, Switch B is the master and hosts with the
default gateway of 202.38.160.200/25 accesses the Internet through Switch B.

Network requirements
z Switch A and Switch B belong to VRRP group 1 with the virtual IP addresses of 1::10/64
and FE80::10.
z Host A wants to access Host B on the Internet, and learns 1::10/64 as its default gateway
through RA messages sent by the switches.
z When Switch A operates normally, packets sent from Host A to Host B are forwarded by
Switch A; when Switch A fails, packets sent from Host A to Host B are forwarded by Switch
B.
