We have two links terminated on router to access the same location, If one link is down the location is still reachable using the 2nd link.
But we don't get any alert if either of the link is down.

As Nagios monitors the availabilty of port only, and in this scenario (when either of the link is down) the router port is up.

How can we get the alert if either of the link is down ?

Both links plugin in to the same router port?

Is there something else that changes on the accessibility of one of the links is down that you could monitor instead (ie one IP becomes unpingable)

1) Both the links are plugged in to same router on different Ports.

2) There is no other change that can be monitored when either link is down.

Also FYI

We monitor the router through local IP and the links are on public IP.

From the scenario you laid out, I would use our Router/Switch wizard and monitor the ports that each of these links are plugged into
