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.

[3Com] vlan 2

[3Com-vlan2] port Ethernet1/0/1

[3Com-vlan2] quit

# Configure VLAN-interface 2.

[3Com] interface Vlan-interface 2 [3Com-Vlan-interface2] ip address 10.100.10.2 255.255.255.0

[3Com-Vlan-interface2] quit

# Create VLAN 3.

[3Com] vlan 3

[3Com-vlan3] port Ethernet1/0/2

[3Com-vlan3] quit

# Configure VLAN-interface 3.

[3Com] interface Vlan-interface 3 [3Com-Vlan-interface3] ip address 10.100.10.4 255.255.255.0

[3Com-Vlan-interface3] quit

# Create VRRP group 1.
