Reviewed this draft as well...

See also previous comments about Normative language

Regarding the draft itself, the only specific comment I might offer is that you
should probably specify in the beginning of section 2 when you first mention
tagging routes with a community that this community is NON-TRANSITIVE. When I
read this, I started thinking about many security concerns if this was not
required to be a non-transitive community, only to find that it was covered on
the following page.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Global Routing Operations Working Group of the
IETF.


	Title           : Auto-Configuration in Virtual Aggregation
	Author(s)       : P. Francis, et al.
	Filename        : draft-ietf-grow-va-auto-03.txt
	Pages           : 6

Virtual Aggregation as specified in [I-D.ietf-grow-va] requires configuration of
a static "VP-List" on all routers.  The VP-List allows routers to know which
prefixes may or may not be FIB- installed.  This draft specified an optional
method of determining this that requires far less configuration.  Specifically,
it requires the configuration of a "VP-Range" in ASBRs connected to transit and
peer ISPs.  An Extended Communities Attribute is used to convey to other routers
that a given route can be FIB-suppressed.  This draft has no changes from the 02
draft.
