RE: [PWE3] Gen-ART review of draft-ietf-pwe3-mpls-eth-oam-iwk-06

[Gregory Mirsky <[e-mail]>]

Dear Huub and Loa,
my brain did s/Reverese/Remote/ by itself. Indeed, 802.1ag and Y.1731 use RDI for Remote Defect Indication, and nothing in Reverse. And that how draft-ietf-pwe3-mpls-eth-oam-iwk-06 should expand RDI as well.

        Regards,
                Greg

Greg,

RFC 6428 expands RDI as:

    RDI: Remote Defect Indication
