BGP路由

边界网关协议 (BGP) 路由负责确定互联网数据传输的最佳网络路径。互联网由数千个私有网络、公共网络、企业网络和政府网络组成，这些网络通过标准化的协议、设备和通信技术连接在一起。当您浏览互联网时，数据在到达目的地之前会经过多个网络。BGP 会检查所有可用的数据传输路径，并选择最佳路径。例如，当美国用户访问一个源服务器位于欧洲的应用程序时，BGP 可以确保通信快速高效。

Equinix 会为您的局域网分配一个私有的自治系统编号 (ASN)。BGP 策略用于选择：

• 默认路由
• 完整路线
• 默认 + 完整路线

IP子网来源

这里描述了EIA服务使用的LAN IP子网的可用选项：

每个 EIA 服务最多可配置 100 个子网。子网可以包含 Equinix 分配的 IP 地址和客户分配的 IP 地址。仅当通告 ASN 由 Equinix 提供时，才允许在同一 EIA 服务上混合使用 Equinix 分配的地址和客户分配的地址。Equinix 分配的地址不能使用客户 ASN 进行通告。

Equinix分配的IP地址

此选项由 Equinix 提供，您必须从 Equinix 购买额外的 LAN IP 子网。

客户分配的IP地址

客户提供的IP地址必须至少为IPv4 /24或IPv6 /48。对于客户分配的IP地址，客户可以使用自己的公共ASN（仅适用于EIA over Dedicated方案）或由Equinix分配的私有ASN。

单端口架构

对于单端口 BGP，Equinix 会为 LAN 分配一个私有的自治系统编号 (ASN)，并分配一个默认的 WAN IP 子网，IPv4 地址为 /30，IPv6 地址为 /64。需要一台支持 BGP 的三层设备。

双端口架构

默认情况下，Equinix 会为 LAN 分配一个私有的自治系统编号 (ASN)，以及两个 /30 IPv4 WAN 子网和两个 /64 IPv6 WAN 子网。双宿主配置需要一对三层设备。

流量工程 - BGP 社群

以下社群对所有 BGP 用户开放：

• 降低本地偏好

  • 65502:80 Set local preference to a lower value than standard customer (above peers, multi homed customer scenario)

• 远程触发黑洞服务

  • 65535:666 Blackhole a single host within customer’s ranges

如果您使用 BGP 并自带 IP 地址，您可以控制路由如何从 AS15830 对外公布，以及流量如何流入您的网络。Equinix 提供以下社区供您添加到前缀中。

• 添加前缀（仅限客户分配的 IP 地址）

  • 65501:nnnn Prepend 1x AS15830 towards a provider or IXs in a metro
  • 65502:nnnn Prepend 2x AS15830 towards a provider or IXs in a metro
  • 65503:nnnn Prepend 3x AS15830 towards a provider or IXs in a metro
  • 65505:nnnn (to be deprecated) Prepend 5x AS15830 towards a provider or IXs in a metro

• 请勿公开（仅限客户分配的 IP 地址）

  • 65509:nnnn Do not announce the prefix towards a provider or IXs in a metro
  • 65509:300 Do not announce to any peer globally
  • 65509:400 Do not announce to any ISP provider globally

后缀“nnnn”可以是提供商 ASN，也可以是以下之一：
