Apparatus and methods of determining configurations for handling
communication path management traffic are disclosed. Respective
communication path management traffic handling configurations of
communication system elements that terminate a communication link, which
is a portion of a communication path, are determined. If the respective
communication path management traffic handling configurations indicate
that the communication system elements have been configured to pass
communication path management traffic associated with the communication
path toward endpoints of the communication path, then communication path
management traffic for managing the communication path is exchanged
through the communication link. Indications of a communication path
management traffic handling configuration may be exchanged between the
communication system elements during establishment of the communication
link.
