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

---R6 ----------- R1 ----------- R5 ---------- R4
       serial Ethernet Ethernet

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
