Routing Front Server for Scalable Internet-Scale Route Table Automation

NetBrain currently collects routing table data through CLI-based retrieval, which becomes impractical at carrier-grade scale where route tables contain millions of entries and full-table pulls can take many hours while placing load on production routers and route reflectors. This enhancement proposes a dedicated front-end component that peers with a customer's routing infrastructure using standard routing protocols, maintains a local copy of the route table, and computes differential summaries locally, exposing only changed, added, or withdrawn prefixes to NetBrain rather than requiring repeated full-table CLI retrieval. Support for multiple routing protocols and optional integration with route monitoring or looking glass data sources would allow flexible, high-fidelity data acquisition. Customers operating at Internet-scale routing volumes would benefit from faster automation cycles, reduced control-plane stress on production devices, and more accurate, timely route change detection for intent-based validation.
