unicast multicast broadcast mac address represents a topic that has garnered significant attention and interest. What is the difference between unicast, anycast, broadcast and .... In IPv6, we have Unicast, Multicast and Anycast. The concept of Unicast and Multicast are same in IPv4 and IPv6, except the changes in IPv6 Layer 3 addresses used for broadcast & multicast and the Layer 2 address used for multicast. Layer 2 address used for IPv6 multicast traffic starts from "33:33:" (in Ipv4, it is "01:00:5e"). ARP - why ARP request is unicast - Cisco Learning Network. Unicast flood the frame out all ports other than the one on which the frame was received.
What do you suppose would happen, at this point, if any other host on the LAN was either a) using the mac but an IP other than 2.2.2.2 or b) using the IP 2.2.2.2 but mac other than 2222.2222.2222? Unknown Unicast vs Broadcast traffic - Cisco Learning Network. Can somebody explain the difference between Unknown Unicast and Broadcast Traffic. In which case, a switch sends a Unknown Unicast and when does it sends Broadcast on receive of an ARP Request??

With this 2 modifications ("no bgp default ipv4-unicast" in both routers and change remote AS for neighbor 2FFF:1:2:4::8 from 222 to 77) your configuration should work (without the "no neighbor activate" commands, you added to your configuration).
DHCP Server Messages (Unicast, multicast or broadcast?). The DHCP operation begins with clients broadcast a request. If the client and server are on different subnets, a DHCP helper or DHCP Relay Agent may be used. Clients requesting renewal of an existing lease may communicate directly via UDP unicast, since the client already has an established IP address at that point.
tcpip - Why ARP request is unicast? I have a Wireshark capture that indicates a unicast ARP request from source to destination. This perspective suggests that, as per my understanding, ARP requests (including gratuitous ARP) use broadcast. In what cases are unicas...
windows - Configuration of Microsoft NLB - Server Fault. It's probably because you're running NLB in unicast mode with only one NIC in the server. In relation to this, there's actually a warning about this every time you open the NLB management interface: Running NLB Manager on a system with all networks bound to NLB might not work as expected.
If all interfaces are set to run NLB in "unicast" mode, NLB Manager will fail to connect to hosts. So either use a NLB ... Equally important, what does the 'no bgp default ipv4-unicast' Command do?. Any other address family needs to be turned on.
For BGP, this means that any config that doesn't specifically mention an address family is assumed to be part of ipv4 unicast.
📝 Summary
As demonstrated, unicast multicast broadcast mac address represents a significant subject worthy of attention. Going forward, ongoing study on this topic can offer additional understanding and value.
