网络工程 - 瞻博网络 MX 路由器之间的点对点 ICMP Ping 丢失 - 吾爱随笔录

我面临关于 1 x 10G 链路的问题（实际上配置为聚合以太网 (ae)，即 ae 链路仅包含单个 10G 链路。

此 ae 链路连接在 2 个瞻博网络 MX960 路由器之间。当我 ping 另一端 MX960 路由器的 P2P IP 接口 IP (ae) 时，我得到数据包丢失。行为是随机的。有时我会迷路（例如 2000 年中的 1 或 2 或 3 个数据包），有时我什至没有得到一滴。行为是随机的。这发生在两个方向，即从 R1 --> R2，反之亦然。

在检查物理接口时，我确认存在任何类型的接口错误。此外，在接口或路由引擎上没有针对我们发送 ping 的 ping 应用防火墙监管器。

以下是 R1 端的 ICMP 快照和接口错误。

我们能知道为什么 IMCP 数据包会被丢弃吗？为什么有时他们会被丢弃，而有时他们不会。
