Monitoring Redundant path routers

[Peter Gutmann]

Why can't you use SNMP for this? The line up and the line down events 
should generate SNMP traps. At the very least, could you use SNMP mib to 
poll the status of the device....

As far as I know, this cannot be done we had to write this into the code 
ourselves.

Hi,
 
I was looking into using Nagios for Enterprise wide monitoring and am very 
impressed with all the capabilities, but ran into following question:

Can Nagios monitor the individual interfaces between the routers in order 
to inform me when a link/interface goes down? I'm mainly interested if 
monitoring Router 3, to have Router 1 and Router 2 as dependencies, but 
also to know if the link between Router 1 and Router 2 goes down, because 
Nagios will be able to reach Router 3 through the link between Router 2 
and Router 3.
 
Any help would be greatly appreciated and if further information is 
required, please feel free to let me know.
