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.
