I used tcpdump to look at the packets. They are on the correct
interface, so this looks like a pimd problem. These packets are on
eth1, so recv_ifindex (eth1) is correct and sock_ifindex=4 (eth2) is
wrong.

pimd.conf contains

interface eth1
 ip pim ssm
 ip igmp

interface eth2
 ip pim ssm
 ip igmp

I tried adding eth0, but that made no difference.

At startup it logs:
