Actually never mind, in pure IP environment you'd still need add-path/diverse-path feature to get the alternate ORR paths across to clients. But actually the whole purpose of ORR was to distribute primary as well as alternate/backup paths, but in an optimal way, as opposed to brute force *all paths(Type1 RDs) or inefficient primary/backup paths(add-paths). The Junos configuration actually allows for manual definition of primary and backup virtual location. (hoping for automatic and/or policy-based primary and best backup selection in future). *The number of paths advertised with this approach can actually be scaled down with careful assignment of RDs among given set of AS-exits. adam netconsultings.com ::carrier-class solutions for the telecommunications industry:: _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
