篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了华为运营商级路由器配置示例 | 配置OptionA方式跨域LDP VPLS示例相关的知识，希望对你有一定的参考价值。
组网需求
如图1，CE1和CE2属于同一个VPLS，分别通过AS100内的PE1和AS200内的PE2接入骨干网。
由于VPLS数量较少，因此本示例采用OptionA方式跨域LDP VPLS，ASBR间的接口被当作AC接口与VSI实例绑定，实现CE1与CE2的互通。
配置思路
-
在骨干网上运行IGP协议实现ASBR与PE之间的互通，并且PE之间要建立隧道。
-
骨干网上配置MPLS基本能力，在同一AS域内的PE与ASBR之间建立动态LSP隧道。如果PE与ASBR非直连，建立LDP远程会话。
-
在PE1、ASBR1、ASBR2和PE2上配置VSI实例，并与AC接口绑定。
操作步骤
1.配置各设备接口的IP地址
