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). VLAN tags are used on trunk interfaces so that the traffic for each 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.

Web12 apr. 2024 · In order to explain Multicasting the best I can and to make it easier for you understand, I decided to break it down into 3 sections: 1) Hardware/Ethernet Multicasting. 2) IP Multicasting. 3) Mapping IP Multicast to Ethernet Multicast. A typical multicast on an Ethernet network, using the TCP/IP protocol, consists of two parts: Hardware ... Web21 oct. 2024 · How Ethernet Addresses Work. Every Ethernet frame carries two addresses – first, the destination, and second, the source. We mentioned that the destination … Web30 ian. 2024 · 2. I think the issue you're hitting is that, by default, a Linux bridge will not forward frames to a destination MAC address in the range 01:80:c2:00:00:00 through 01:80:c2:00:00:0f. The IEEE reserved this block of addresses for protocols that must not be forwarded by a MAC bridge. Protocols such as LLDP, LACP, xSTP, etc., are all in this … show me a picture of a bloodhound dog
