Figure 20 Configuring VRRP group attributes
Verifying the configuration
After the configuration, Host A can ping Host B. You can view the VRRP group information on
GigabitEthernet 0/1 on Device A and Device B. In VRRP group 1, Device A is the master and Device B
is the backup. Device A is responsible for forwarding packets sent from Host A to Host B.
If the interface that connects Device A to the Internet fails, Host A can still ping Host B. In this case, the
VRRP group information on the two devices shows that Device A becomes a backup with the priority 80
and Device B becomes the master. Device B forwards the packets from Host A to Host B.
