What address is used for Ethernet broadcasts?
Broadcast is possible also on the underlying data link layer in Ethernet networks.
Frames are addressed to reach every computer on a given LAN segment if they are addressed to MAC address FF:FF:FF:FF:FF:FF.
Ethernet frames that contain IP broadcast packages are usually sent to this address..
Can you broadcast at the layer 2 level?
You can have broadcasts at Layer 2. … The broadcast address is FF. FF.
Is a router layer 2 or 3?
Routing is a layer 3 function. Packet switching is a layer 2 function. If a router can packet switch as well as route, it is a layer 2 and layer 3 device. … Anything upper layer protocol is going to sit on software and hardware that also function at the lower levels, but routing is done at 3.
When a device sends a Layer 2 broadcast the destination MAC address in the frame is set to?
When a device sends a Layer 2 broadcast, the destination MAC address in the frame is set to all binary ones. A frame with a destination MAC address of all binary ones is received by all devices in the broadcast domain.
What is a Layer 3 broadcast address?
Layer 3 Broadcasts. Similar to a L2 broadcast, a Layer 3 broadcast is simply a special IP address set as the Destination IP address for a particular packet. Unlike L2 broadcasts, however, there are two different options for what you use as the Destination IP address for a Layer 3 Broadcast.
Is Lan a Layer 2?
LAN is more commonly a reference to a layer-2 network but is sometimes used for a layer-3 network aka subnet as well.
Can a Layer 2 switch support VLANs?
You can configure one or more VLANs to perform Layer 2 bridging. Thus, MX Series routers or EX Series switches can function as Layer 2 switches, each with multiple bridging, or broadcast, domains that participate in the same Layer 2 network. You can also configure Layer 3 routing support for a VLAN.
Is IP a Layer 2?
Generally speaking, Layer 2 is a broadcast Media Access Control (MAC) MAC level network, while Layer 3 is a segmented routing over internet protocol (IP) network. To better understand both layers, let’s dig a little deeper into the OSI model.
Is a hub a Layer 2 device?
Hubs are basically layer 1 devices without any intelligence and do not separate collision or broadcast domains. Switches are basically layer 2 (MAC addresses) with some intelligence and separate collision domains.
Which is true about a Layer 3 broadcast?
L3 broadcast will be sent to a broadcast ip address (last ip of a subnet), so it can be recieved by all ip adresses of that subnet. Example 192.168. … 1.255) will be sent only to ip addresses of that subnet, devices on the same physical domain that are not part of that ip subnet will drop the traffic.
Why would you need to know the MAC address of a device?
The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. … Changing a MAC address can be necessary in some cases to keep an Internet connection working.
What is the MAC address of FFFF FFFF FFFF FFFF?
ffff. ffff , this is the special reserved MAC address indicating a broadcast frame. This is what makes an ARP Request a broadcast. Had Host A chosen to send this frame using a specific host’s MAC address in the destination, then the ARP request would have been unicast.
