Web30 ian. 2024 · How does a typical l2 switch treat broadcast or multicast Ethernet frames? Layer 2 switches send frames to a physical or logical interface based on the destination MAC address. If a Layer 2 switch does not have a mechanism to learn about where to send multicast messages, it treats all multicast frames as broadcast, which is to say it floods … WebMulticast is a form of broadcast at layer-2, and it is limited, just like broadcast, to a layer-2 domain (VLAN).

A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (layer 3 for OSI) for Internet Protocol Version 4 (IPv4) or Version 6 (IPv6) multicast. Ethernet frames with a value of 1 in the least-significant bit of the first octet of the destination address are treated as multicast frames and are flooded to all points on the network. This mechanism constitutes multicast at the data link layer. This mechanism is used by IP multicast to achieve one-to-many transmission for IP on Ethernet networks. Modern Ethernet controllers filter received packets to reduce CPU load, by looking up the hash of a multicast destination addres… Web13 mar. 2024 · Multicast frames are sent to a specific group of devices that have joined a multicast group, while Broadcast frames are sent to all devices on the network.

WebIt refer to "IG bit" that is present in the Ethernet Frame. The IG bit distinguishes whether the MAC address is an individual or group (hence IG) address. In other words, an IG bit of 0 indicates that this is a unicast MAC address, an IG bit of 1 indicates a multicast or broadcast address. Share Improve this answer Follow Web1 mai 2015 · Frames addressed to those MAC addresses are by default flooded to all ports in the vlan by ethernet switches, but as an optimization switches can implement IGMP snooping in order to limit which ports receive the frames based on which ports have actually subscribed to the multicast group.
