DN42 Service

:::info{title="描述"}
选择性建立 Peer，请先提交您的 ASN 审核 
**不保证**可用性和稳定性，容易受到不可抗力的影响 
随时可能更改路由收发策略，恕不另行通知
:::

:::danger{title="Peer 前须知"}
您必须实施有效的路由震荡抑制，如 FlapAlerted with StayRTR、FRR Dampening 
禁止用于违规跨境传输，发现违规直接拉黑 AS 
您至少需要有 **30** 个 Peer 数量，有完整的网络架构 
**不接受单终端、HomeLan接入**，如您对外提供公共网络诊断服务，可例外 
**非常不推荐跨运营商 Peer，国内跨运营商丢包率>30%，除非您知道您在做什么** 
**请不要跑太多流量，跑太多会随时拔线**

目前仅支持 WireGuard 方式连接，默认 MP-BGP + Extend Next Hop + IPv6 Link-Local 方式连接 
需要 Peer 留下你的节点信息，看到后会手动添加，1RTT 完成 Peering 
**如您的 peer 连续离线 14 天以上且未另行通知原因，会被清理** 
**由于部分节点没有IPv4或v6，隧道是由 Cloudflare WARP 提供，请留意MTU值。MTU取决于clearnet传输数据使用的是什么IP协议** 
 
Currently, only WireGuard connections are supported. The default connection method is MP-BGP + Extend Next Hop + IPv6 Link-Local. 
If you need a peer, please leave your node information. We will add it manually upon seeing it. Peering is completed in 1 RTT. 
**If your peer remains offline for more than 14 consecutive days without providing a reason, it will be removed.** 
**Since some nodes do not have IP version 4 or 6, the tunnel is provided by Cloudflare Warp; please pay attention to the MTU value. The MTU depends on the IP protocol used for clearnet data transmission.**
