Figure 6-20, hosts on a LAN are dual-homed to RouterA and RouterB through
The host uses RouterA as the default gateway to connect to the Internet. When RouterA
becomes faulty, RouterB functions as the gateway. This implements gateway backup.
After RouterA recovers, it becomes the gateway within 20s.

Assign an IP address to each interface and configure a routing protocol to ensure network
connectivity.
Configure a VRRP group on sub-interfaces of RouterA and RouterB, set a higher priority
for RouterA so that RouterA functions as the master to forward traffic and set the
