锐捷MPLS的配置
1）全局开启MPLS转发功能
Ruijie(config)#mpls ip
2）全局开启LDP标签分发协议
Ruijie(config)#mpls router ldp
Ruijie(config-mpls-router)#ldp router-id interfaceloopback 0 force
//建议此处指定LDP的router-id的时候，使用loopback接口且使用force的强制属性， force说明立即生效
3）开启接口的标签交换能力
Ruijie(config)#int gigabitEthernet 0/0
Ruijie(config-GigabitEthernet 0/0)#label-switching
//缺省情况下，三层接口只能识别IP数据包，如果不开启标签交换能力的话，是不能识别MPLS标签包。
4）接口下开启LDP协议
Ruijie(config)#int gigabitEthernet 0/0
Ruijie(config-GigabitEthernet 0/0)#mpls ip
Ruijie(config)#show mpls ldp parameters /查看LDP详细信息
Ruijie(config)#show mpls ldp discovery detail /查看LDP发现情况
Ruijie(config)#show mpls ldp neighbor /查看LDP邻居关系
Ruijie(config)#sh mpls ldp bindings /查看LIB表
Ruijie(config)#sh mpls forwarding-table /查看LFIB表
mpls ip/全局开启MPLS功能
mpls router ldp/开启LDP标签分发功能
Idp router-id interface Loopback 0 force/强制指定LDP的route-id为loopbacko
label-switching/接口开启MPLS标签交换功能
mpls ip接口开启LDP协议
recursive-route lookup Isp/让流量跌带到LSP隧道
