Methods, systems, and computer program products for managing and selectively distributing routing information in a routing node are disclosed. In one implementation, a method for selectively distributing routing information in a routing node includes organizing internal signaling resources are organized so as to facilitate the efficient mapping of signaling system 7 (SS7) message transfer part (MTP) signaling protocol attributes to Internet protocol (IP)-based signaling resources. A routing status information sharing hierarchy is defined, which enables routing status information to be efficiently shared among members of a signaling mateset group. Members of a signaling mateset replicate and distribute SS7 MTP network management information across non-MTP signaling connections, such as IP connections.
