ESRP Tracking Example

The following figure is an example of ESRP tracking.

ESRP Tracking

To configure VLAN tracking, use the following command:
configure esrp esrp1 add track-vlan vlan1

Using the tracking mechanism, if VLAN1 fails, the ESRP master realizes that there is no path to the upstream router via the master switch and implements an ESRP failover to the slave switch.
To configure route table tracking, use the following command:
configure esrp esrp1 add track-iproute 10.10.10.0/24

The IPv4 route specified in this command must exist in the IP routing table. When the route is no longer available, the switch implements an ESRP failover to the slave switch.
To configure ping tracking, use the following command:
configure esrp esrp1 add track-ping 10.10.10.121 frequency 2 miss 2

The specified IPv4 address is tracked. If the fail rate is exceeded, the switch implements an ESRP failover to the slave switch.
