DoD label allocations and longest-prefix matching for FECs means that summarization can be used in the a Seamless MPLS architecture: https://tools.ietf.org/html/rfc5283 https://tools.ietf.org/html/rfc7032 Cheers, James. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
