配置OptionC方式跨域BGP VPLS示例
ASBR上无需创建和维护VPLS。当每个AS都有大量的跨域VPLS时，可选择这种方案，防止ASBR成为阻碍网络进一步扩展的瓶颈。
组网需求
如图10-30，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。
当每个AS内有大量的跨域VPLS时，可以配置采用OptionC方式跨域BGP VPLS。在OptionC方式跨域BGP VPLS中，ASBR上不再维护VPLS标签块信息，而是PE之间直接交换VPLS标签块信息。
配置思路
采用如下的思路配置OptionC方式跨域Kompella VPLS：
在骨干网上运行IGP协议，使同一个AS域内的各设备能互通。
在骨干网上使能MPLS，在PE与ASBR之间建立动态LSP隧道，并且在ASBR之间的接口上也要使能MPLS。
同一AS的PE和ASBR之间建立IBGP。
在各ASBR之间配置EBGP，在ASBR上需配置路由策略，使能标签路由功能。在PE1和PE2之间建立MP-EBGP对等体关系。
在PE1和PE2之间创建VSI实例，接入CE。
数据准备
为完成此配置例，需准备如下的数据：
PE及ASBR上的MPLS LSR-ID。
PE上创建的VSI实例名、路由标识RD及收发路由属性VPN-Target。
PE上绑定VSI实例的AC接口。
ASBR上使用的路由策略。
操作步骤
- 配置各设备接口的IP地址
