    COMMENT:
    ----------------------------------------------------------------------

    Hi,

    I found this document easy to read and understand.

    A couple of minor comments:

    4.3.  UDP Checksum

       By default, UDP checksum MUST be used when LISP-GPE is transported
       over IPv6.  A tunnel endpoint MAY be configured for use with zero UDP
       checksum if additional requirements in Section 4.3.1 are met.

    This paragraph could probably be moved/merged into section 4.3.1?

[FM] good catch. We have moved it there in rev-17

    4.4.  DSCP, ECN and TTL

       When a LISP-GPE router performs Ethernet encapsulation, the inner
       header 802.1Q [IEEE.802.1Q_2014] VLAN Identifier (VID) MAY be mapped
       to, or used to determine the LISP Instance IDentifier (IID) field.

    This text doesn't appear to be related to DSCP, ECN or TTL.  Perhaps tweak the
    title of this section to cover this text?

[FM] Good point. Changed to " DSCP, ECN, TTL, and 802.1Q". 

Thanks,
Fabio
