Hi I tried to work with the ip multicast help-map, but fail, does anyone
know why?
---R6 ----------- R1 ----------- R5 ---------- R4

R6 Ethernet join group 239.0.0.1,
With no transfer, R5 and R4 ping 239.0.0.1 get replied.
after converted multicast ---> broadcast ----> multicast can't ping any more
