All things related to multicast

Hi Michael,

Embedded RP  is viable solution for applications who cannot leverage SSM 
.  It uses the the 3 out 4 flag bits to indicate the rp address is embedded 
in the group address..ie RPT flags are set to 1.
Please let me know if you need further information wrt cisco's implementation.

Thanks
Tsege
