Communicating information between core and edge network elements

摘要

In particular embodiments, a network element filters information sent to a neighboring network element. In the embodiments, the core network element may determine whether the neighboring network element is an edge network element or a core network element. If the neighboring network element is an edge network element, the core network element may set a filter, remove traffic engineering information according to the filter, and send the remaining information to the neighboring network element.
