摘要
分析了BGP MPLS VPN模块的需求,该模型包括三个主要子模块:LDP模块、转发模块、转发表组装模块,分析发它们的工作原理,提出了模块设计与实现思路,将VRF表、FNT表、IML表三表合并为一个转发表,由操作码决定查询的转发条目,简化了对路由信息的管理,提高了查表效率.
Analyzes the needs of BGP MPLS VPN modul.The model include three main Sub-units,that are the unit of LDP,Forwarding and Forwarding Table unit.Meanwhile,analysis forward operation principle and puts thoughts of design and impletation.Besides,puts VRF-table,FTN-table and IML-table into a Fowarding-table of which the Forwarding-ietm is decided by Operation-cord,so that it simplifies the management of Route-information,improve the look-up table efficiency.
