Abstract
A technique for managing control protocol information in a network node involves identifying messages as control protocol messages and checking the messages to see if the messages carry any updated control protocol information. If a control protocol message carries updated control protocol information, then the message is forwarded to a control protocol processor and if the message does not carry any updated control protocol information then the message is dropped before getting to the control protocol processor. The determination as to whether or not a control protocol message carries updated control protocol information can be made by generating a digest from a control protocol message and comparing the digest to a digest generated from a previously received control protocol message. A mismatch between the newly generated digest and the digest from the previously received control protocol message is an indication that the current message carries updated control protocol information.
