Does IOS 12.4 provide a mechanism to disable the PIM Assert Process? If so, how?

I would recommend against blocking that multicast address as that would handicap any PIM communication coming in that interface. I know of no way to disable just the Assert messages in IOS. neteng

An alternative to disabling the PIM assert process might be to use an ACL to block PIMv2 Type 5 messages in/out to 224.0.0.2. Any ideas on how this ACL would look if it can be done?
Correction: 224.0.0.13 for PIMv2. 224.0.0.2 is PIMv1

on a related problem - anyone know how to stop IOS sending out multicasts to
224.0.1.40 for the AutoRP function?it bhaves OK with a pure IOS environment - but causes lots of "invalid RP join" messages when it propagates to other PIM v2 / BSR type devices...
Stephen,
I think you'll need to implement the 'ip multicast boundary filter-autorp' command. It works as a bi-directional ACL to block auto- rp traffic for the multicast groups in the ACL. Let's say you want to stop the traffic from flowing through ethernet0/0:
ACL for all multicast groups: access-list 1 permit 224.0.0.0. 15.255.255.255
interface e0/0 ip multicast boundary 1 filter-autorp
