静态MPLS实验

拓扑规划

配置要求

  1. 所有路由器建立IGP(OSPF),将物理接口和环回口宣告到进程下;
  2. 配置mpls lsr-id为自己环回口,全局和接口下使能mpls;
  3. 手动建立静态mpls(来回方向);
  4. 检查建立状态和标签转发路径。

相关命令

全局相关配置:

#
mpls lsr-id 1.1.1.1      // 配置lsr-id为环回口地址
mpls                           // 全局开启mpls

#
interface GigabitEthernet0/0/1                  // 接口开启mpls
mpls
