4、，我们一直遵循如下原则： 充分保证实施方案整体的可靠性； 全面考虑网络过渡过程的各方面因素，尽可能地减少对现网业务的影响； 在实施过程中进行必要的测试，保证整个实施过程的正确性。 本期 cn2 业务延伸网络连接目标包括物理连接层面、路由层面、安全与管 理层面三个主要层面，总体目标如下： 物理连接层面: 实现 cn2 与 ip 城域网 vpn 互连。 路由层面: 建立 cn2 与南京 ip 城域 vpn 网的路由连接并保障路由安全。 comment a1: comment a2: 南京电信城域网南京电信城域网 asbr 对接对接 cn2 asbr 割接方案割接方案 第第 4 页页 共共 58 页

5、页 网络现状描述网络现状描述 目前中国电信 cn2 网络江苏南京节点有 t640 两台作为 c 设备，有 gsr12416 两台作为 s 设备。其中 c 设备已与 ip 城域网核心 cisco12416 设备采用 oc192 端口互联；s 设备已与 ip 城域网 vpn 设备的 vrr 采用 ge 端口互联，目前采用 两台华为 ne40 作为 asbr。这两台 ne40 兼做南京城域网 vpn 的 vrr，南京城域 网和 cn2 使用 option a 方式实现跨域 vpn。南京城域网 vpn 使用 as 号 64512，城域网 as 为 64660。 南京城域网和 cn2 使用 option

6、 a 方式实现跨域 vpn，在这种方式下作为 asbr 的 pe 需要管理所有 vpn，这将导致 pe 上的 vpn-ipv4 路由数量非常庞 大，对 pe 设备的要求非常高。 本次割接实现 asbr 从华为 ne40 割接至南京城域网利旧的两台 gsr12416（原城域网核心设备）上，采用性能更优的 gsr12416 作为跨域 vpn 的专用 asbr，以满足网络扩展的要求，完成 cn2 mpls vpn 与南京电 信 mpls vpn 城域网之间跨域对接工作，与 cn2 pe 设备采用 pos 链路互联， 所以在 cn2 pe 侧还需要各增加一块 pos 板卡，互联路由（实为 pece 路

7、由） 采用 ebgp（每客户一个会话） ，跨域互联采用 option a 方式。 本次割接需要在保证传输资源已经到位的情况下进行。 本次实施对城域网的业务无影响。 ynl ne40 割接割接步骤步骤 本次割接工作要求传输及尾纤布放工作(鼓楼 gsr12416cn2 鼓楼 pe)提前 comment a3: comment a4: 南京电信城域网南京电信城域网 asbr 对接对接 cn2 asbr 割接方案割接方案 第第 5 页页 共共 58 页页 准备，并调通相应互联链路。 一城域网鼓楼一城域网鼓楼 gsr12416gsr12416 初始化配置初始化配置 基本配置基本配置 int loopba
