Network Bgp Diagnostics

affaan-m/everything-claude-code

This is a read-only BGP troubleshooting workflow that walks you through neighbor state checks, route policy inspection, and transport validation without touching session resets or config changes. It covers the full state machine (Idle, Active, OpenSent, Established) and includes specific show commands for route-maps, prefix-lists, and AS-path filtering. The included Python parser handles the common case where the rightmost column in show bgp summary is either a state name or a prefix count. What I like here is the discipline: it explicitly calls out that clearing sessions and changing authentication belong in a change window, not in your 3am triage script. If you're building BGP automation or just want a checklist that won't make things worse, this is a solid starting point.

Network BGP Diagnostics

Use this skill when a BGP session is down, flapping, established with missing routes, or advertising unexpected prefixes. The default workflow is read-only evidence collection; policy and reset actions belong in a reviewed change window.

When to Use

  • BGP neighbors are stuck in Idle, Connect, Active, OpenSent, or OpenConfirm.
  • A session is Established but expected prefixes are missing.
  • A route-map, prefix-list, max-prefix limit, or AS path policy may be filtering routes.
  • You need before/after evidence for a BGP change.
  • You are reviewing automation that parses BGP summary output.

Read-Only Triage Flow

  1. Identify the exact neighbor, address family, VRF, and local/remote ASNs.
  2. Capture summary state and last reset reason.
  3. Prove reachability to the peer source address.
  4. Check route policy references before assuming transport failure.
  5. Compare advertised, received, and installed routes where the platform supports those commands.
