If the interface is being assigned a new gateway, examine the contents of the last packet sent from the gateway. The gateway’s address is found in an upcoming message. Look for a display of the local interface from the remote gateway. Correct the remote gateway if needed. If the interface is timing out, verify that no transmissions have been received over this interface for the last 3 minutes. If no transmissions are found, this is correct behavior for NCPROUTE, and the physical lines or remote gateways should be examined to determine the cause of the problem.
