HCIP实验5-mpls实验

搭建实验拓扑图

要求

全网可达

实验开始

配置IP地址及环回

这里已经配置好,不再赘述,具体可参考之前实验

OSPF,RIP

r7配置OSPF,r8配置RIP,这里已配置好 

配置mpls

步骤:

1、IP可达--- 使用路由协议全网可达
2、配置MPLS – LDP
[r2]mpls lsr-id 2.2.2.2      //必须先定义mpls的router-id，要为本地设备的真实ip地址，且邻居可达，因为该地址将用于建立TCP会话，建议使用环回地址
[r2]mpls                        //再开启mpls协议
[r2-mpls]mpls ldp         //再激活LDP协议
[r2-mpls-ldp]q
之后需要在所有标签经过的接口上开启协议
[r2]interface GigabitEthernet 0/0/1
[r2-GigabitEthernet0/0/1]mpls            //先开启MPLS
[r2-GigabitEthernet0/0/1]mpls ldp      //再激活LDP协议
[r2]route recursive-lookup tunnel        //开启隧道递归
