Is SNMP enabled on the router?

Can you ping that router on that address from the SNMP server?

Is the community string configured on the router really the word

Can you snmpwalk the router form the box running MRTG?

In your MRTG configuration, the word "community" in the line
"community at" should be replaced with the actual snmp
community string on the router.  This typically defaults to the word
"public" for read-only access but can (and should) be changed to
something different.  Think of it as a password.
