Symptoms
Configuring VRRP with ping tracking
Environment
Extreme XOS
Cause
The specified IP address is tracked. If the fail rate is exceeded, the switch implements a VRRP failover to the backup. A VRRP node with a priority of 255 may not recover from a ping-tracking failure if there is a Layer 2 switch between it and another VRRP node. In cases where a Layer 2 switch is used to connect VRRP nodes, we recommend that those nodes have priorities of less than 255.
Resolution
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 ping tracking.
configure vrrp vlan vlan1 vrid 1 add track-ping 10.10.10.121 frequency 2 miss 2

You can use any “reachable” IP address to track. Say a default gateway, an outside router or whatever as long it is reachable.
