Abstract
A method system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) network domain. At least two Backbone Edge Bridges (BEBs) of the PLSB domainare provided. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path defined within the PLSB domain. An inter-node trunk is provided in the PLSB domainfor interconnecting the at least two BEBs. A phantom node is defined in the PLSB domain. The phantom node has a unique address in the PLSB domainand is notionally located on the inter-node trunk one hop from each of the BEBs. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress subscriber packet destined for the client system is forwarded to the client system through the connection in the first network domain.
