3、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。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V

4、PN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 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P

5、OS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)提前准备，并调通相应互联链路。一城域网鼓楼GSR12416初始化配置基本配置Int loopback0 Ip add *.*.*.*.
