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:
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.
