有關(guān)客戶側(cè)的BGP路由器的配置參考：
有關(guān)VLANID： VLANID是客戶自定義的internalVLAN,不同的客戶可以使用相同的VLANID，對(duì)于IXP來(lái)說(shuō)，會(huì)有一個(gè)唯一的S-tag進(jìn)行標(biāo)記，不需要客戶配置網(wǎng)絡(luò)底層的S-tag。詳見(jiàn)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.
