Network requirements
Host A needs to access Host B on the Internet. The default gateway of Host A is
■
10.1.1.10/24.
Router A and Router B belong to VRRP standby group 1, whose virtual IP
■
address is 10.1.1.10.
When Router A works normally, packets from Host A to Host B are forwarded
■
through Router A. When VRRP finds that there is a fault on the upper link of
Router A through Track, packets from Host A to Host B are forwarded through
Router B.
