示例：为使用用户定义的网格组的 LDP VPLS 配置 BGP 自动发现
此示例介绍如何配置用户定义的网格组，用于 LDP VPLS 的 BGP 自动发现，如转发同等类 （FEC） 129 中所述。FEC 129 使用 BGP 自动发现来传达端点信息，因此您无需手动配置伪线。您可以在边界路由器上配置网状组，以便对自动全网状且共享相同信令协议（BGP 或 LDP）的 PE 路由器集进行分组。您可以配置多个网格组，以便将每个全网状 LDP 信号或 BGP 信号 VPLS 域映射到一个网格组。
要求
开始之前，为 LDP VPLS 配置 BGP 自动发现。请参阅 示例：为 LDP VPLS 配置 BGP 自动发现。
此示例的硬件和软件要求与 示例的要求相同： 为 LDP VPLS 配置 BGP 自动发现。您需要根据此示例中使用的拓扑结构调整示例配置。
概述
FEC 129 的网状组配置与 FEC 128 的网状组配置非常相似。
请注意 FEC 129 的以下差异：
每个用户定义的网格组都必须具有唯一的路由识别符。请勿使用在层次结构级别上为
[edit routing-intances]默认网格组定义的路由识别符。每个用户定义的网格组都必须有自己的导入和导出路由目标。
每个用户定义的网格组都可以有一个唯一的第 2 层 VPN ID。默认情况下，为 VPLS 路由实例配置的所有网格组使用的第 2 层 VPN ID 与您在层次结构级别上
[edit routing-instances]配置的 VPN ID 相同。
配置
CLI 快速配置
要快速配置网格组，请复制以下命令，删除所有换行符，然后将命令粘贴到每个设备的 CLI 中。
