multicast problem

satellite modem--------------------------router----------------server(multicast station)

|

| fast ethernet0/0

cisco 2611

| fast ethernet0/1

|

pc

when pc connected to satellite modem,it can receive multicast from server

but when pc connected to cisco 2611,it can receive nothing

debug ip mpacket on cisco 2611 get nothing

it seems multicast packet get to the satellite modem,but the cisco 2611 doesn't receive it

because the satellite modem stop the igmp packet, I use igmp static-group

cisco 2611 config:

ip multicast-routing

int f0/0

ip address 172.101.5.1 255.255.255.252

ip pim dense-mode

ip igmp static-group 239.16.5.144

int f0/1

ip address 172.21.1.1 255.255.255.0

ip pim dense-mode

ip igmp static-group 239.16.5.144

ip route 0.0.0.0 0.0.0.0 172.101.5.2

Re: multicast problem

How does the packet (based on your topology) get to the sat modem without transversing the router? Are you sure you're logging your debugs to the terminal? In any case, some troubleshooting with a support engineer is probably best here.
