Hi, all:
I'm implementing a multicast-related router-protocol. When a packet
enques, I need to determine whether it's a multicast packet. how can I do?

If you can access the packet header, a packet is a multicast packet if

#define MULTICAST_ADDRESS 0xE00

p-daddr() = MULTICAST_ADDRESS


Take a look in MAODV code for ns2. It uses this definition in recv() function
