Hi Jeff, to update the IANA considerations section by replacing TBD1 with the actual MAC address? I see two small allocation ranges for in the Unicast MAC addresses: 00-52-02 to 00-52-12 Unassigned (small allocations) ..... 00-52-14 to 00-52-FF Unassigned (small allocations)
Also, can we change the wording in the Reference column from "BFD over VXLAN" to "Control channel in NVO3"? That would be helpful to the work on OAM in Geneve.
