The output shows that Router A is operating as the master in VRRP group 1 to forward packets from
Host A to Host B.
# Disconnect the link between Host A and Router A, and verify that Host A can still ping Host B.
(Details not shown.)
# Display detailed information about VRRP group 1 on Router B.

The output shows that when Router A fails, Router B takes over to forward packets from Host A to
Host B.
# Recover the link between Host A and Router A, and display detailed information about VRRP

The output shows that after Router A resumes normal operation, it becomes the master to forward
packets from Host A to Host B.
Multiple VRRP groups configuration example
To implement load sharing between the VRRP groups, you must manually configure the default gateway
1::10 for some hosts and 1::20 for the other on the subnet 1::/64.
Network requirements
Router A and Router B form two VRRP groups to implement load sharing and mutual backup. VRRP group
1 uses the virtual IP address 1::10/64 to provide gateway service for some hosts on the subnet 1::/64,
