Normally, multiple VRRP groups are used in actual use.

Port Tracking Configuration Examples

Network requirements
VRRP group 1 comprises two switches, which act as the master and the backup.
The actual IP addresses of the master and the backups are 10.100.10.2 and 10.100.10.3
respectively.
The master is connected to the upstream network through its Ethernet 1/0/1 port. The backup is
connected to the upstream network through its Ethernet 1/0/2 port.
The virtual router IP address of the VRRP group is 10.100.10.1.
Enable the port tracking function on Ethernet 1/0/1 port of the master and specify that the priority of
the master decreases by 50 when Ethernet 1/0/1 port fails, which triggers new master being
determined in the VRRP group 1.
