Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0036] In the cross-domain VPN, because the PE only maintains the route of the VPN connected to it. Therefore, the VPN-IPv4 routes received by the ASBR from different PEs may come from the same VPN and still belong to the same subnet, so there is the possibility of further aggregation. However, the prior art does not aggregate possible VPN-IPv4 routes on the ASBR, but publishes all the received VPN-IPv4 routes to other autonomous systems.

[0037] Therefore, in the embodiment of the present invention, on the ASBR, according to the original routes received from multiple PEs, the original routes with the same RD and belonging to the same subnet are aggregated to generate aggregated routes, and a label is...

Abstract

The invention discloses one router polymer method applied in network composed of self-government system boundary router, wherein, each ASBR and multiple providers are connected with device PE and comprises the following steps: ASBR receives multiple PE original routers with same router character and same original router for polymer to generate polymer router to align one label for each router andto add label on polumer router to generate polymer router. The invention also discloses one message transfer method and one boundary router.

Description

technical field [0001] The present invention relates to routing protocol technology in the field of data communication, in particular to a message forwarding method and an autonomous system in a Border Gateway Protocol / Multiple Protocol Label Switch Virtual Private Network (BGP / MPLS VPN, Border Gateway Protocol / Multiple Protocol Label Switch Virtual Private Network) border router. Background technique [0002] BGP / MPLS VPN is a mechanism that allows service providers (SP, Service Provider) to use their own backbone network to provide VPN services to customers. BGP / MPLS VPN uses the BGP protocol to advertise VPN routes on the service provider's backbone network, and uses the MPLS protocol to forward VPN packets on the service provider's backbone network. The MPLS protocol is a protocol for forwarding MPLS packets by using the labels in the MPLS packets, and VPN packets are also MPLS packets. [0003] figure 1 It is a block diagram of the BGP / MPLS VPN network model. Such a...
