LSP启用保护的LSP保护选项在RSVP协议里,启用保护选项配置本group下的BGP session的属性,inet是启用IP路由支持,此项为默认启用,inet-vpn是启用l3mbgp-vpn路由支持,启用任意非INET属性,会将inet禁用配置routing-instances配置routing-instances的VRF将逻辑接口加入到routing-instances里配置RD，确认RD在整个routing-instance里是唯一的配置RT，确认RT在整个routing-instance里是唯一的，并且同一个routing-instance里的多个PE上RT要相同配置PE-CE之间的静态路由，这里要注意，在PE-CE之间为以太网连接的情况下，一定要加一个特定的静态路由，目的地址为PE-CE之间的互联的IP子网，下一跳地址为对端CE的接口IP地址配置PE-CE之间的OSPF路由，这里要注意，一定要加一个特定的POLICY，目的是为了将从对端PE学到的VPN路由注入PE-CE之间运行的OSPF协议，使得两端的CE互相能学到对方的路由。
