Is it OK to submit one big patch once I'm done, or would the core developers prefer smaller, more incremental patches? One patch would be easier for me.
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-routing .. see page 40-4 in chapter 40, under the heading "PIM Versions." Maybe that will help (I know it's not much).
