当跨域VPLS数量比较少时可以采用此方案。

组网需求

如图10-27，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BGP VPLS，ASBR间的接口被当作AC接口与VSI实例定，实现CE1与CE2的互通。

图10-27 配置OptionA方式跨域BGP VPLS组网图

本示例中interface1，subinterface1.1，inerface2，subinterface2.1分别代表GE1/0/0，GE1/0/0.1，GE2/0/0，GE2/0/0.1。

配置思路

采用如下的思路配置OptionA方式跨域BGP VPLS示例

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。
PE与域内的ASBR建立MP-IBGP对等体关系。
在PE1、ASBR1、ASBR2和PE2上配置VSI实例，并与AC接口绑定。

数据准备

为完成此配置例，需准备如下的数据：

PE、ASBR的MPLS LSR ID。
CE-ID和CE range。
CE上接入PE的接口IP地址。PE上接入CE的接口无需配置IP地址。
PE上VSI的RD和VPN-Target，VSI所属的Site ID。

操作步骤

配置各设备接口的IP地址
