Network requirements
Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its
■
default gateway.
Router A and Router B belong to standby group 1 with the virtual IP address of
■
202.38.160.111.
If Router A operates normally, packets sent from Host A to Host B are
■
forwarded by Router A; if Router A is in work, but when its interface Ethernet
1/1 which connects to the internet is not available, packets sent from Host A to
Host B are forwarded by Router B.
