Implementing Multicast

You can implement the IGMP, DVMRP, and PIM multicast protocols on Extreme Networks devices using simple CLI commands as described in this document. A basic configuration process involves the following tasks:

  1. Configuring the VLANs and IP interfaces on which you want to transmit multicast.
  2. Enabling the multicast protocol(s) on configured interfaces.

For PIM, you must also configure a unicast routing protocol, such as OSPF. For both DVMRP and PIM for IPv4 to operate, IGMP must be enabled. For PIM for IPv6 to operate, the Multicast Listener Discovery (MLD) protocol must be enabled.
