A system monitors signaling data transmitted between routers. The system
includes at least one router that communicates signaling data via a
session with at least one other router. The system also includes a
network element that receives a copy of the signaling data via a control
session established with the at least one router. The sessions, including
the control session, can be border gateway protocol (BGP) sessions. The
network element can also operate as a BGP control server or a centralized
policy manager.
