Reports the number of routes for which every alternate next-hop protects against failure of just the outgoing link to the primary next-hop, not necessarily the next-hop router itself. Admins distinguish this from node-protected routes because link protection alone won't help if the actual neighboring router fails rather than just the link to it. A route showing up only in ipFrrLinkProtectedRoutes, and not ipFrrNodeProtectedRoutes, tells an admin that failure of the next-hop router itself, as opposed to the link, would not be covered by fast-reroute.
