ABSTRACT:
A first device generates a first knowledge digest encoding first configuration information that is associated with communications to a second device. The first device receives from the second device a message that includes a second knowledge digest encoding second configuration information. The first device compares the first knowledge digest to the second knowledge digest and produces an indication if the second configuration information encoded in the second knowledge digest is not a subset of the first configuration information encoded in the first knowledge digest.
