有關客戶側的BGP路由器的配置參考：
有關VLANID： VLANID是客戶自定義的internalVLAN,不同的客戶可以使用相同的VLANID，對於IXP來說，會有一個唯一的S-tag進行標記，不需要客戶配置網絡底層的S-tag。詳見下文配置示例（僅供參考）：
Specify C-tags (VLAN ID)
Customerneed tospecify 2 C-tags to identify the P2P subinterface traffics. C-tag isgenerally aVLAN ID, you can specify it from 1 to4094. Any number is ok. Differentcustomers can use same C-tags, allowoverlap. C-tag is inner VLAN,when packetspassed to IXP, IXP will add an S-tagto the packets, as outer VLANID. S-taguniquely identified a customer’s trafficthrough IXP network.
