摘要：
Described is a method for managing flow of protocol information in a node of a hierarchical network in which the protocol information is communicated between network nodes in topology state elements. The method includes checking topology state elements generated by the node to identify protocol information encapsulated therein, and selectively allowing transmittal of the topology state elements from the node to lower levels of the network based on the protocol information identified.
