Some comments on draft-ietf-v6ops-v6inixp-03.txt

Hello, Roque,

Here's some feedback on the aforementioned I-D.

* Editorial *

Introduction:

>    Most Internet Exchange Points (IXP) work on the Layer 2 level, making
>    the adoption of IPv6 an easy task.

s/work on/work at/


I found it hard to parse this sentence:

> This document clarifies the impact of IPv6
>    on a new or an existing IXP that may or may not fit any particular
>    deployment.



Section 2:

> However, some management

Include a (Informative)  reference to the SNMP spec.

BTW, in this text:

You meant something like "...will typically configure interfaces as
dual-stack, although independent interfaces could be possibly used for
each version of IP"?

Rephrase as "If IXP participants are already using Virtual LAN (VLAN)
tagging on those interfaces of their routers that are facing the IXP
switch...."

Maybe s/capital cost-free/inexpensive/ ?

P.S.: More in the pipeline!
