VRRP Tracking

The following figure is an example of VRRP tracking.

Configure VLAN tracking, as shown in Adding and Deleting Tracked VLANs .
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.
Configure route table tracking, as shown in Adding and Deleting Tracked Routes.
configure vrrp vlan vrrp1 vrid 2 add track-iproute 10.10.10.0/24

The route specified in this command must exist in the IP routing table. When the route is no longer available, the switch implements a VRRP failover to the backup.
Configure ping tracking, as shown in Adding and Deleting Tracked Pings.
configure vrrp vlan vrrp1 vrid 2 add track-ping 10.10.10.121 frequency 2 miss 2

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.
