Auto Detect Implementation in VRRP 71

# Configure an IP address for VLAN-interface 2.

[SwitchA] interface vlan-interface 2

[SwitchA-Vlan-interface2] ip address 10.1.1.1 24

#Enable VRRP on VLAN-interface 2, and set the virtual IP address of the VRRP group to 10.1.1.10.

[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.10

#Set the VRRP priority of Switch A to 110, and specify to decrease the priority by 20 when the result of detected group 9 is unreachable.

This configuration procedure only provides the auto-detect and VRRP related
n configuration. To use auto detect function properly, a route to Switch A must
already exist on Switch E.
