Alex,

	Unfortunately I believe I did ask the wrong question.  My problem is
that I cannot find any OID that will give you the total number of
routes, the only thing I have found so far is the standard routing
table entries (Source, Destination, Next Hop) when trying to poll a
Cisco device (12000 GSR, 6500MSFC, 8400).  Currently the only way I
have been able to extract the information that I need is to write a
script to go out and poll the device and calculate the number of
routes.

If you know where/how to get the numbers, then it's just another
setup with 'Options[x]: gauge' .

Find two OIDs, know which instance to use (may be zero) and specify
on the command line.  The FAQ contains an example that uses the OIDs
for ifInOctets and ifOutOctets (without using gauge BTW), you should
copy that example, changing the OIDs and using the gauge option.

If you already knew this, you asked the wrong question and should
retry, this time pointing out what it is that fails.
