All things related to multicast

Hi.

Is it possible to switch off auto-rp on a cisco router?
I'm trying to stop announce messages to groups 224.0.1.39 and 224.0.1.40
from arriving to a determined interface with the interface command:

ip multicast boundary 10

Standard IP access list 10
    10 deny   224.0.1.39
    20 deny   224.0.1.40
    30 permit any

But it's not working, the router still receives the auto-rp announce
messages coming from that interface:

- debug ip pim auto-rp
Sep 22 15:57:07: Auto-RP(0): Received RP-discovery, from X.X.X.X, RP_cnt 1,
ht 181
Sep 22 15:57:07: Auto-RP(0): Added with (224.0.0.0/4, RP:X.X.X.X), PIMv2 v1

Is there another way to do it?

Thank you,
Luis Marta.
