Path count management

Abstract:

This disclosure describes techniques for managing path counts at a router. The techniques include monitoring available storage space at a router for storing per prefix routes. In an instance where the available storage space at the router may be inadequate to support continued, stable network operations, the techniques include reducing an amount of per prefix routes that are advertised to the router. The techniques may also include withdrawing previously advertised per prefix routes from the router. As such, path count management concepts may help prevent overload of storage space at a router.
