192 CHAPTER 20: VRRP CONFIGURATION GUIDE
Networking and
Configuration
Requirements
■ There are two switches, the master and the backup, in VRRP group 1.
■ The IP addresses of the master and the backup are 10.100.10.2 and
10.100.10.3 respectively.
■ The master is connected with the upstream network through port Ethernet
1/0/1 that belongs to VLAN 2, and is connected with a Layer 2 switch through
Ethernet 1/0/2 that belongs to VLAN 3.
■ The virtual IP address of the VRRP group is 10.100.10.1.
■ Enable the port tracking function on Ethernet 1/0/1 of the master and specify
that the priority of the master decreases by 50 when Ethernet 1/0/1 fails, which
triggers a new master election in VRRP group 1.
■ On the backup, the configurations related to the upstream and downstream
device connection, and the configurations related to the VRRP group have
been finished. The configuration procedures are omitted here.
