BRI and IP Mulicast

Hello All !

I have heard from several sources that Multicasting packets cannot be forwarded over ISDN , is this correct ?

If so , is there a workaround for this ie tunnelling the packets ?

Thanks for all help !

Hello,

I am not aware of any restrictions running multicast over ISDN. Are you running into a specific problem while implementing this, or is it more a theoretical question ?

Regards,

Re: BRI and IP Mulicast

no specific problems but am unable to get it working by using the PDF's on the cisco website....

can you supply a basic config that would allow acceptance on incoming calls and multicast packets to a BRI interface please?

It would help us solve your problem if you would post the config from at least one of the routers (and might be helpful to have configs from both sides of the connection).

If you are using a dialer map are you including the parameter "broadcast" in the dialer map? That is essential to sending multicast when using dialer map.
