frame relay broadcast handling

could someone please explain the concept of how frame relay can handle a broadcast . So far i know

frame relay dose not do broadcast's
the broadcast keyword must be used when doing static mapping to enable a static mapping be considered for broadcast

i guess to simplify my question ..

In frame relays default form i.e using inverse arp will frame relay not work with any routing protocols do the mappings have to be static to enable routing protocols to function correctly

furthermore say a packet received on the address 224.0.0.10 will it be sent out every interface that has been staticly configured with the broadcast keyword

This is not necessarily true; from MY understanding P2P still forward multicasts as broadcasts.

furthermore say a packet received on the address 224.0.0.10 will it be sent out every interface that has been staticly configured with the broadcast keyword Correct; so if you had:

frame-relay map ip 10.0.0.1 101 broadcast
frame-relay map ip 10.0.0.2 102 broadcast frame-relay map ip 10.0.0.3 103EIGRP packets will be forwarded to 10.0.0.1 & 10.0.0.2

It's worth noting that the broadcast keyword doesn't actually enable broadcasts....it enables pseudo-broadcasts. It basically takes broadcast and multicast traffic and puts it in a unicast packet to the other side.
