If the router can accept SNMP queries then you should be able to use
http://nagios.manubulon.com/snmp_int.html and rather than use MRTG I
would recommend PNP4Nagios as this can get the performance data from
Nagios.

Note that check_snmp_int.pl will write temporary files to keep a
record of counters so be careful of ownership and permissions when
testing.   Also, you need to specify the 64-bit counters otherwise
they wrap round back to zero too frequently.
