Information

 
TitleConfiguring VRRP and VLAN tracking
Symptoms
Configure VRRP and vlan tracking in case that one vlan fails the VRRP configuration will failover to the backup switch
Environment
Extreme XOS
Cause
Use VRRP and in case that one vlan fails permit the switch to failover the VRRP configuration to the backup switch.
Resolution
Here is an configuration example:

Switch A is the IP address owner, and Switch B is configured as the backup. The configuration commands for switch A are as follows:

configure vlan vlan1 ipaddress 192.168.1.3/24
create vrrp vlan vlan1 vrid 1
configure vrrp vlan vlan1 vrid 1 priority 255
configure vrrp vlan vlan1 vrid 1 add 192.168.1.3
enable vrrp


The configuration commands for switch B are as follows:

configure vlan vlan1 ipaddress 192.168.1.5/24
create vrrp vlan vlan1 vrid 1
configure vrrp vlan vlan1 vrid 1 add 192.168.1.3
enable vrrp


Configure VLAN tracking.

configure vrrp vlan vrrp1 vrid 2 add track-vlan vlan1

Using the tracking mechanism, if VLAN1 fails, the VRRP master realizes that there is no path to the upstream router through the master switch and implements a VRRP failover to the backup.
