摘要：
In methods and apparatus for acquiring VPN reachability information at a node of a data network, a VPN reachability information request is transmitted from a requesting node. The VPN reachability information request comprises a VPN identifier. Other nodes of the data network receive the VPN reachability information request and, if they have reachability information relevant to that VPN, they transmit such information to the requesting node where it is received and stored. The invention can be used in MPLS VPN architectures.
