Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method performed by a primary border node (BN) for internetworking two network domains such that Internet Protocol (IP) addresses are efficiently assigned and advertised across a network domain boundary, the two network domains including an access network that implements MultiProtocol Label Switching Transport Profile (MPLS-TP) and a core network that implements Internet Protocol (IP) or MPLS, wherein the access network is coupled to the core network via th…
