Hcip实验

 要求：全网可达\n\n

二、实验开始

配置IP地址以及环回（这里已经配置好具体可参考之前实验）

OSPF,RIP（r7配置OSPF，r8配置RIP，这里已经配置好）配置mpls步骤：\n1.IP可达—使用路由协议全网可达\n\n2.配置

MPLS-LDP\n\n[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\n\n[r2]mpls          //再开启mpls协议\n\n[r2-mpls]mpls ldp      //再激活LDP协议\n\n[r2-mpls-ldp]q\n\n之后需要在所有的标签经过的接口上开启协议\n\n[r2]interface GigabitEthernet 0/0/1\n\n[r2-GigabitEtherent0/0/1]mpls     //先开启MPLS\n\n[r2-GigabitEtherent0/0/1]mpls ldp     //再激活LDP协议\n\n[r2]route recursive-lookup tunnel      //开启隧道递归
