snmp get from a router

i am trying to create some code to read an snmp oid from a router. i will then use that value to do some display fun.

so im stuck the snmp query for a remote device. i have looked at agentuino library but that seems to add snmp host functionality to the arduino not handle the querying of another device.

what im really looking for are code examples of an arduino querying some device on the network and returning a value . any ideas? my googlefu in this has not been strong
