Thanks mate, but that was not really my question. I was interested in finding out whether RFC3973 is supported. The Cisco IOS has supported PIM-DM for some time but it has undergone various incarnations in terms of IETF drafts - I wanted to know whether the latest RFC on it is supported.
There were a few changes in the RFC and the drafts leading up to it, such as:
- the use of the Assert mechanism on p2p links, which was restricted to multiaccess segments in older drafts
- the use of prune rate-limiting on multiaccess segments, which was restricted to p2p links in older drafts
I just wanted to know what was the last draft that was implemented by Cisco.
I have subsequently received some info from a Cisco employee (who is on the IETF PIM mailing lists) who has advised that Cisco is no longer introducing any new features to PIM-DM (which is probably quite reasonable since PIM-SM is the preferred approach now).
