Normally, multiple VRRP groups are used in actual use.
Port Tracking Configuration Examples
Network requirements
z VRRP group 1 comprises two switches, which act as the master and the backup.
z The actual IP addresses of the master and the backups are 10.100.10.2 and 10.100.10.3
respectively.
z 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.
z The virtual router IP address of the VRRP group is 10.100.10.1.
z 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.
