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
