Border gateway protocol procedures for multi-protocol label switching and layer-2 virtual private networks using Ethernet-based tunnels |
摘要 |
Described are a network device and method for distributing routing information for a virtual private network (VPN) application through a packet-switched network (PSN) from a first provider edge (PE) router to a second provider edge (PE) router. An Ethernet switched path (e.g., a Provider Backbone Transport (PBT) tunnel) is established between the first and second PE routers. The first PE router is at a source end of the Ethernet switched path and the second PE router is at a destination end of the Ethernet switched path. A BGP (Border Gateway Protocol) message is sent from the first PE router to the second PE router. The BGP message contains routing information for a VPN route in a VPN supported by the PSN. An association between the VPN route in the VPN and the Ethernet switched path is determined from the routing information in the BGP message. |
