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

Authors, thank you for the detailed and thorough service model, especially for sections 6 and 7, it shows a good example to follow for model development.

A few comments and nits:

References to NMDA (8342) and tree diagrams (8340).

s2: VPWS definition seems to have a missing word - established as a logical [connection?] through a PSN.

s2: B-U-M vs BUM abbreviation, BUM seems to be more widely used in VPLS and EVPN references.

s3.1: IPLS reference RFC 7436.

s/VxLAN/VXLAN throughout the document.

s5.2.1: s/leave/leaf.

s5.2.1: references to E-Line and E-LAN would be good to have, MEF 6.

s5.2.2.4: MAC-VRF, s/arerequired/are required

s5.2.2.4: H&S disjoint topology would require more than two RTs in total, one per hub and at least one for sites.

s5.2.5: first paragraph: three frame types are supported - could you clarify?
Did you mean three frame types need to be supported?

s5.3: Terminology - exterior interfaces vs ACs.

s5.3: last paragraph: the site may support single homed or multi-homed [access?] - seems to be a word missing.

s5.3.2.2.1: s/802.1AH/802.1ah, a reference would be good.

s5.3.2.2.3: Micro-BFD reference RFC7130.

s5.3.2.2.6: cfp-802.1-ag vs cfm-8021-ag

s5.6.2: s/ALPHA-2/ISO 3166.

s5.10.1: s/dot1p/802.1p (or 802.1D).

s5.10.3: CE to CE frame modification - why SHOULD NOT form is used? What would happen if it  gets modified - as there is a common practice of not trusting customer CoS marking.

s5.15: s/REST/RESTCONF

s5.16.1, 5.16.2, 5.16.3: the use of EBGP, MP-BGP terms - it is just BGP, does it need to be emphasized?

s6: s/operatorpolicy/operator policy

s6: s/itscontrol/its control

s6: NETCONF/YANG ecosystem - maybe just YANG based ecosystem?

s7: s/Netconf/NETCONF
