All things related to multicast

["João Paulo Malheiro de Barcelos" <>]

Hi!

I am having trouble implementing my multicast through a CISCO 7513
router. 

There are some FastEthernet interfaces and an ATM interface.

When the Multicast traffic comes in through the FastEth, it is
perfectly distributed and everybody gets the mcast packets. 

But when the traffic comes in through the ATM interface, the other
interfaces don´t receive the mcast packets. 

When I give a SHOW IP MROUTE, I see that the router learns multicast
groups coming from the  ATM, and yet there are no outgoing interfaces
in these groups, even though I have made requests.

Isn´t the ATM supposed to be transparent??

Has anybody had the same kind of problem?

I would really appreciate some help

Thanks
