RouteDiff

RouteDiff is a web app (with an optional lightweight desktop agent) that continuously compares your intended routing policy to what the network is actually doing across BGP/OSPF/IS-IS. It ingests configs and live routing tables, then produces human-readable diffs: which prefixes changed best path, where attributes shifted (local-pref, MED, communities), and which devices diverged from baseline. It focuses on the unglamorous but expensive problem: silent routing drift caused by ad-hoc changes, vendor quirks, and partial rollouts. Alerts are tied to impact (which sites/VRFs/prefix groups) rather than noisy “route changed” spam. It also generates a “blast radius” report for a proposed change by simulating policy deltas against current RIB snapshots. This is a traditional app with AI-assisted explanations: AI summarizes diffs and likely causes, but the core is deterministic parsing and comparison so operators can trust it.
