This draft is ready for publication, but has a few NITS:

The draft includes more than a few grammatical errors. I will not call out each. Please run a grammar checker over it.

Section 2:
 "Tunnel Type".  The same codepoint 0x0B that IANA has assigned for [RFC8556] for the new tunnel type "BIER" is used for EVPN as well."

  This sentence needs to be reworked (e.g., for [RFC8556] for)

""Tunnel Identifier".  When the "tunnel type" field is "BIER", this
      field contains two subfields.  The text below is exactly as in
      [RFC8556]."

   When is the tunnel type not "BIER"?

   Two subfields or three?

6. Security Considerations

How do you know that this protocol does not introduce new security consideration. If you don't tell me how, I will just have to take your word for it. One or two sentences explaining how you came to this conclusion might help.
