many thanks for your reply. but i was wondering i could could map even all
unicasts to a host on a particular protocol and port number to convert it
into a multicast to feed the multicast domain.. i've tried using helper-map,
configs look okay but couldnt figure out a method to do testing with it. did
permit udp any any broadcast-2-multicast-2broadcast. did forward protocol
udp
and enabled directed-broadcast..did a ping on the local segment x.x.x.255
and 255.255.255.255 ..got reply from the local broadcast domain but the
remote never replied..

Hello

check this command "r2(config-if)#ip multicast helper-map"

r2(config-if)#ip multicast ?
  boundary Boundary for administratively scoped multicast addresses
  helper-map Broadcast to Multicast map OR Multicast to Broadcast map
  rate-limit Rate limit multicast data packets
  tagswitch Enable IP Multicast Tagswitching
  ttl-threshold TTL threshold for multicast packets

Thanks

Abdallah
