Hi,

A multicast MAC address should always start with 01-xx-xx.......
For Eg:vendor Componet of Cisco is 0x00-00-0C and a multicast address asigned to Cisco is 0x01-00-0C.So does a mulitcast application on a host can turn on that multicast address of Cisco from 0x00-00-0C to 0x01-00-0C ? or we need seperate multicast NIC card for that ?
