    1、引言

    各企业用户在开通SHIXP提供的服务如开放对等、选择对等等服务时，需要注意哪些事项，并对自身的网络进行哪些配置？以下是一些关于技术方面的建议，希望在首次接入时能够提供一定的帮助。

    2、接入基本规范

    2.1 端口支持

    接入端口速率是否支持聚合备注
    1GE是自适应，全双工
    10GE是自适应，全双工
    100GE是自适应，全双工

    2.2 接入端口限制

    • 包括BUM流量抑制：允许转发的带宽大小分别进行限制。
    • 对MAC地址过滤，只处理合法接入用户的MAC(变更时需通知交换中心)。
    • 以太网报文允许：0x0800 - IPv4，0x0806–ARP，0x08dd - IPv6，0x8809 – LACP。
    • ARP流量不超过CPCAR限制。
    • 接入的路由器上应禁止接入交换中心的设备通过如DHCP、STP、CDP、VTP等协议。

    2.3 与RS路由交换要求

    Route Server1Route Server2
    ASN146761146761
    IPv4103.183.26.1103.283.26.2
    IPv62400:5F60:0:8::12400:5F60:0:8::2

    具体要求参见“Route Server规范”。

    3、接入准备

    SHIXP技术部会根据不同业务需求，对用户进行一定程度的网络资源分配，具体分配的网络资源会在商务合同签署后，以书面资料或邮件的形式给到用户相关部门，需要用户自行明确的信息（包含SHIXP分配的） 如下：

    • 用户自身互联设备信息、设备的端口号、端口类型。
    • 用户需要开通的业务类型。
    • 用户接入SHIXP的链路数量及聚合情况。
    • 用户的AS号和IP信息（需经过CNNIC认证）。
    • 用户与交换中心协商对应的vlan ID。
    • 开放、选择对等中发送的IP段。
    • 与SHIXP互联的IP地址（SHIXP分配）。
    • 交换中心提供的Community列表。

    4、BGP相关配置参考
