Why it matters: BGP zombies and excessive path hunting disrupt Internet routing, leading to packet loss, increased latency, and network instability. Understanding these phenomena is crucial for network engineers to maintain reliable and efficient global connectivity.
- •BGP zombies are routes that remain active in the Internet's Default-Free Zone despite being withdrawn, causing traffic misdirection and operational issues.
- •These zombies typically arise from slow BGP route processing, software bugs, or missed prefix withdrawals.
- •Path hunting is the process where BGP routers search for the best path after a more-specific prefix is withdrawn, falling back to a less-specific one.
- •The Minimum Route Advertisement Interval (MRAI) intentionally delays BGP updates, extending the duration of path hunting and increasing the chance of zombies.
- •Zombies can lead to packets being trapped in loops or taking inefficient routes, impacting network performance and reliability.
- •Cloudflare observes BGP zombies affecting BYOIP on-demand customers using Magic Transit.
Why it matters: This article highlights how subtle misconfigurations in standard libraries (like Go's HTTP/2 client) can lead to critical interop issues and trigger network defenses, emphasizing the need for deep understanding of protocol implementations.
- •HTTP/2 misconfigurations can lead to denial-of-service attacks like PING floods, triggering defenses such as Cloudflare's ENHANCE_YOUR_CALM GOAWAY frame.
- •An internal microservice communication issue was traced to a Go standard library HTTP/2 client sending excessive PINGs, causing connection closures.
- •The problem stemmed from a subtle interaction between Go's http.Transport PingTimeout and ReadIdleTimeout settings, leading to continuous PINGs.
- •Debugging required "on the wire" analysis using packet captures or GODEBUG=http2debug=2 logging to identify the client's actual behavior.
- •Proper configuration, ensuring PingTimeout is longer than ReadIdleTimeout or disabled when ReadIdleTimeout handles liveness, is crucial to prevent such HTTP/2 PING floods.
