Thanks Steve. Yeah unfortunately the link isn't too helpful to me, as it doesn't show all the PIMv1 packet formats, which is really what I'm interested in. Anyway, I'll submit one patch through bugzilla when I feel it's ready. The full extent of the changes may depend on the captures I have available for testing though. - Chris -----Original Message----- From: wireshark-dev-bounces () wireshark org [mailto:wireshark-dev-bounces () wireshark org] On Behalf Of Stephen Fisher Sent: Tuesday, January 19, 2010 11:57 AM To: Developer support list for Wireshark Subject: Re: [Wireshark-dev] PIM On Jan 19, 2010, at 9:28 AM, Maynard, Chris wrote:

One big patch is fine if that's what works best for you. Thanks for improving that dissector!
Assuming that's OK, I would like to regression test it as much as possible before submitting it. I have some PIM captures,
but
could use some more. Ideally, I could get captures depicting all message types and with all the different options, but I'll take what I can get. If you have capture file(s) of PIM traffic, especially ones that include lots of options, I would appreciate it if you could post them for my testing.
I don't see any PIM captures in my personal library, sorry.
Lastly, I am currently working off RFC's 4601 and 3973, but these
RFC's
describe only PIMv2. I don't have any information whatsoever on
PIMv1.
The PIM dissector gives the following link as a source of information for PIMv1; however, the link no longer works: http://www.mbone.de/training/Module3.pdf. Does anyone have
information
on PIMv1? It looks to be very similar to PIMv2 except implemented
under
IGMP; however none of the IGMP RFC's describe it. As indicated by
http://www.juniper.net/techpubs/software/junos/junos72/swconfig72-multic
ast/download/pim-intro.pdf, "In fact, no current RFC describes PIMv1
at
all: The drafts have all expired, and PIMv1 was never issued as an official RFC."
Hmm.. my brain isn't working too well trying to remember the differences. I thought I remembered, then realized I was thinking of IGMPv1 versus v2;). I did find this link: http://www.scribd.com/doc/2584135/Cisco-3750-Configure-IP-multicast-rout ing .. see page 40-4 in chapter 40, under the heading "PIM Versions." Maybe that will help (I know it's not much). Steve CONFIDENTIALITY NOTICE: The contents of this email are confidential and for the exclusive use of the intended recipient.
