Disable PIM Assert Process
 

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

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

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.

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 <acl#>
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

HTH,
