默认情况下,公网终结点的端口号为20000+(你的ASN的后4位)。

假如你的 ASN 为 4242420001 ,则我会默认将与你互联的 Wireguard 接口的侦听端口设定为 20001 。

By default, the port number of clearnet endpoint equals to 20000+(last 4 digits of your ASN)

For example, if you have your ASN 4242420001, I’ll set listen port 20001 on the Wireguard interface towards to you.

  • 使用 IPLC 等方式拥有与你想要连接的 SERNET-DN42 节点同一地域的 IP 地址且延迟可以接受。(Use methods like IPLC to obtain an availiable IP address in same region of the one SERNET-DN42 node you want to peer with, and the latency is also reasonable.)



路由策略(Routing Policy)


SERNET-DN42 的默认路由策略为 Hot-Potato Routing。这是 BGP 的默认路由策略,选取 AS-PATH 最短的路径,在此基础上尽可能使用 EBGP 路由。

而对于带有地域团体属性的路由,SERNET-DN42 采取 Cold-Potato Routing 的策略。尽可能将报文在自治系统内部传输,以期求基于地域的更优的流量路径。

The default routing policy of SERNET-DN42 is Hot-Potato Routing. This is the default routing policy of BGP, choose the path with shortest AS-PATH, and use EBGP route as much as possible on this basis.

For those routes with region communities, SERNET-DN42 take Cold-Potato Routing policy. Transmit the packet within AS as much as possible to optimize the traffic path based on region.
