I used this configure:
ip multicast-routing
ip pim rp-address 192.168.10.1
interface FastEthernet0/0
description link to Patong
ip address 172.20.246.46 255.255.255.252
ip pim sparse-mode
load-interval 30
duplex auto
speed auto
!
interface FastEthernet0/1
description link LAN Decode
ip address 192.168.101.1 255.255.255.0
ip pim sparse-mode
ip igmp static-group 239.70.10.10
load-interval 30
duplex auto
speed auto
I found it high cpu.
