METHODS AND APPARATUS FOR IMPLEMENTING VPN SERVICES
摘要
Implementation of a VPN service such as a VPLS (Virtual Private Local area network Service) is performed utilizing a two-stage process. Two-stage process involves providing notification of whether a PE (Provider Edge) router in a label-switching network has VPLS capability. Notification can include broadcasting a message from a PE router to remote PE routers in the label-switching network to indicate whether the broadcasting PE router is VPLS enabled. A second stage of the two-stage process involves, based on receiving a notification that a PE router is VPLS enabled, generating a query message to discover a set of VPLS instances to which the broadcasting PE router belongs. A given PE router generating the query message can identify other PE routers in the label-switching network associated with the same VPLS for purposes of setting up the VPLS in the label-switching network.
