Trying to find the reason IGMP messages are sent over wan links.

Auto-rp uses IGMP messages for its groups, but the following address (148.5.5.1) is the loopback of R5 sending IGMP to serial address of R2 (148.5.235.2)

R5(s0/0)-----(s0/0.235)R2

Aug 25 11:47:41: %SEC-6-IPACCESSLOGRP: list 103 denied igmp 148.5.5.1 (Serial0/0.235 ) -> 148.5.235.2, 6 packets

Aug 25 11:52:41: %SEC-6-IPACCESSLOGRP: list 103 denied igmp 148.5.5.1 (Serial0/0.235 ) -> 148.5.235.2, 7 packets

Any help appreciated.
