sgichk_routetable

This plugin checks the route table and reports on any new routes that appear or any old routes that disappear. When you have a complicated network with multiple redundant routes, backup routes via VPN tunnels, etc, it's sometimes nice to know any time your route table changes.

This plugin was written before I'd started doing snmp queries directly from perl. It assumes it should use the snmpbulkwalk command to fetch route tables and should probably be used to check only certain core routers. Someday I'll rewrite it to do it's own snmp queries instead of using snmpbulkwalk and to use memcached to store old route tables instead of temp files.
