Integrate third-party web looking glass to compare external and edge routes

NetBrain currently does not provide a way to query external third-party web looking glass services and compare the resulting external route data against the routes observed on an organization's own edge routers. This enhancement would allow users to query a third-party looking glass source directly and present that external route information alongside the corresponding edge device routing data for comparison. Internet service providers and other network operators would benefit from faster validation of external route visibility and quicker identification of routing discrepancies at their network edge, reducing manual cross-referencing between external tools and internal route tables.
