AD review of draft-ietf-l2vpn-etree-frwk

["Adrian Farrel" <[e-mail]>]

Authors,

I have conducted my usual AD review of your draft having received a
publication request. The purpose of the review is to catch significant
issues before the I-D advances to IETF last call and IESG evaluation.

This document seems fine to me and I only have three nits. I will start
the IETF last call and raise these nits as last call comments and you can
address them with any other comments you receive.

Thanks for the work,
Adrian

Section 2.2 has

   An E-Tree service has one or more Root ACs and many Leaf ACs.

I suggest that "many" is not a necessary part of the definition 
although it may be probable in deployments. For the definition I think
you need:

   An E-Tree service has one or more Root ACs and at least one Leaf AC.

Section 2.3.1 para 2

Figure 1 shows two notations "E-Tree". The associated arrows do not 
make it clear what is the extent of the E-tree since the top one and 
the bottom one show different edge points. Can you tidy that up?
