Router - configure Track command

Unanswered Question

Hello Experts,

I need to configure a router so that it can detect when one gateway is down.

I was told that there is a command named "track" that sends a constant ping to detect if the gateway is up. If the ping is not detected then it will be sent via route-map to the other gateway. Anyone has some links to read on this? Or perhaps a configuration example using track?

Thanks,

Randall

Yes tracking does work the way you heard, but it doesnt just use icmp but also udp or http get request. Tracking can be used in a number of ways viz with hsrp, routing, PBR etc.


If you are configuring HSRP & need to use tracking to monitor the interfaces then follow this link:

If you want to use PBR with tracking, then refer this:

hope that clarifies.
