Dear all,

I have got into knots for presentment of ALL-ZERO-MAC's encapsulation in EVPN MAC/IP Advertisement route.

draft-bonica-l3vpn-orf-covering-prefixes-03 defines the "Default MAC Route ":

   o  Default MAC Route (DMR) - An EVPN MAC/IP Advertisement Route with
      MAC Address length equal to 0.

But draft-rabadan-l2vpn-dci-evpn-overlay-01 said:

2.5.1 Use of the Unknown MAC route to reduce unknown flooding 

      The solution suggested in this document is based on the use of an
      "Unknown MAC route" that is advertised by the Designated Forwarder
      DC GW. The Unknown MAC route is a regular EVPN MAC/IP
      Advertisement route where the MAC Address Length is set to 48 and
      the MAC address to 00:00:00:00:00:00 (IP length is set to 0).


Can we use a uniform way?


Regards,
Shunwan (Vincent)
