Dear WG:

Any thoughts?

At first glance, it looks like there may be an editorial error.  Do you
agree?  If so, which should it be: “…two different sets…” or “…the first
set…”?

Thanks!

Alvaro.

The following errata report has been submitted for RFC3376,
"Internet Group Management Protocol, Version 3".

You may review the report below and at:

--------------------------------------
Type: Editorial
Reported by: Wim De Smet <wim.1.de_smet@nokia-sbell.com>

Section: 6.2.1

Original Text
-------------

When a router filter-mode for a group is EXCLUDE, the source record
list contains two types of sources. The first type is the set which
represents conflicts in the desired reception state; this set must be
forwarded by some router on the network. The second type is the set
of sources which hosts have requested to not be forwarded. Appendix
A describes the reasons for keeping this second set when in EXCLUDE
mode.

Corrected Text
--------------
[see note]

Notes
-----
Appendix A.3 contains the following:
One of the ways to accomplish this is for routers to keep track of
all sources desired by hosts that are in INCLUDE mode even though the
router itself is in EXCLUDE mode.

Appendix A.3 makes clear that in EXCLUDE mode we need to keep track of the
set of hosts that *are* desired (i.e. set A in section 6.4 or the "first
type" in this paragraph). The second set (set B in section 6.4) is the set
that will be reported to upstream routers, it is not the set which is
needed for smooth switching to INCLUDE mode (the behavior described in
appendix A). I believe that the intended description may have been
"Appendix A describes the reasons for keeping two different sets when in
EXCLUDE mode". At the very least, it appears to be set A (the "first set")
which is intended in appendix A.
