Summary: Almost Ready


Major Concerns:

None


Minor Concerns:

Section 3.1: This solution is for customers that have already chosen 
SD-WAN, and this offers GENEVE as well.  Please avoid the comparison
to other inter-connection services.
    
Section 9.2: What hash function will be used with HMAC?

Section 9.3: How are the keys set up?  IKEv2?


Nits:

Throughout: s/public internet/public Internet/

Section 1: Please expand "Cloud DCs" on first use.

IDnits offers a suggestion:

  -- The document has examples using IPv4 documentation addresses according
     to RFC6890, but does not use any IPv6 documentation addresses.  Maybe
     there should be IPv6 examples, too?
