This is an OPS-DIR review of BGP based Multi-homing in Virtual Private LAN
Service - draft-ietf-bess-vpls-multihoming

This is a complex document but it is reasonably understandable

two minor text questions/suggestions
section 3.5
current text: For the use case where a single PE provides connectivity to a set
of  CEs from which some on multi-homed and others are not, only single
pseudowire MAY be established. would it be better to replace the last phrase
with "at most one pseudowire MAY be established” or at least "only a single
pseudowire MAY be established" later in the same paragraph add an "a" before
"single pseudowire"

section 6 end of sentence add "the procedures"
"...co exist in the network with PEs or Route Reflectors that do support the
procedures.

on the operations side: I do not see specific operational issues but do worry a
bit about the level of complexity getting in the way of reliable configuration
and operation but I do not see what can be done about that I trust there will
be an associated document that details monitoring hooks (e.g. a YANG module) so
that an operator could watch what is going on
