I understand the difference between unicast and multicast, group, is in the middle on a router forwarding unicast will only out of a port is forwarded and will be based on the multicast address and multicast forward from multiple ports, but in the final stages of the incoming to the destination host LAN, the router will broadcast, all hosts will receive the data packet, I understand, right? O teach bosses,

CodePudding user response:

Connection between a host is typically switches, not routers, switches in the arp table, table shows which MAC address in which port, so the data is coming, switches will be according to the data objective MAC address of the head, forward it to the specified port, not broadcasting,
