摘要： A primary border node (BN) and a standby BN are provided for internetworking two network domains, such that connectivity between the two network domains is maintained when a failure occurs in one of the network domains. The two network domains include an access network that implements MPLS-TP and a core network that implements IP, MPLS, or a combination of both. The primary BN establishes a tunnel from itself to the standby BN, and re-directs network data traffic from itself to the standby BN via the tunnel when it detects that an access node has switched connection from the primary VN to the standby BN. The primary BN also monitors its connections to the core network, and signals access nodes to switch to the standby BN if a failure is detected in these connections.

摘要： IP addresses are efficiently assigned and advertised across the boundary of two network domains. The two network domains include an access network that implements MPLS-TP and a core network that implements IP, MPLS, or a combination of both. A primary BN at the domain boundary receives an assignment of an IP prefix for a VPN that connects a set of CEs to one or more SNs. The IP prefix represents a pool of IP addresses. The primary BN assigns only one IP address to both itself and a standby BN for the VPN to minimize the use of assigned IP addresses. The primary BN assigns the other IP addresses to the CEs in the VPN. The primary BN then advertises the IP prefix into the core network to enable routing of network data traffic across the network domain boundary.
