AV Line of Fully Managed Switches M4250 Series Main User Manual IPv4 multicast routing and the IPv4 multicast route table Multicast is best suited for video and audio traffic requiring multicast packet control for optimal operation. Multicast for IPv4 includes support for IGMPv1, IGMPv2, and IGMPv3. Communication from point to multipoint is called multicasting. The source host (point) transmits a message to a group of zero or more hosts (multipoint) that are identified by a single IPv4 destination address. Although the task can be accomplished by sending unicast (point-to-point) messages to each of the destination hosts, multicasting is the preferred method for this type of transmission. A multicast message is delivered to all members of its destination host group with the same best-efforts reliability as regular unicast IPv4 messages. The message is not guaranteed to arrive intact at all members of the destination group or in the same order relative to other messages. Display the IPv4 multicast route table The multicast routing (Mroute) table includes information about the source IPv4 address, group destination IPv4 addresses, the incoming and outgoing interfaces, next hops to which IPv4 packet must be forwarded, and supported protocols. To display the IPv4 Mroute table: 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login page displays. 3. Click the Main UI Login button. The main UI login page displays in a new tab. 4. Enter admin as the user name, enter your local device password, and click the Login button. The first time that you log in, no password is required. However, you then must specify a local device password to use each subsequent time that you log in. The System Information page displays. 5. Select Routing > Multicast > Mroute Table. The Mroute Table page displays. 6. To refresh the page, click the Refresh button. The following table describes the nonconfigurable fields on the page.
