source (Multicast VLAN Registration)


Hierarchy Level


Configure a VLAN to be a multicast source VLAN (MVLAN), and specify the IP address range of the multicast source groups.

To configure a data-forwarding VLAN as an MVLAN, you also configure one or more multicast receiver VLANs (MVR receiver VLANs) with hosts that might be interested in receiving traffic on the MVLAN for the specified multicast groups. You can configure a VLAN as either an MVLAN or MVR receiver VLAN, but not both at the same time.


On EX4300 and EX4300 multigigabit switches, you can configure up to 10 MVLANs, and up to a total of 4K MVR receiver VLANs and MVLANs together. On EX2300 and EX3400, you can configure up to 5 MVLANs and the remaining configurable VLANs can be MVR receiver VLANs.

The remaining statement is explained separately. See CLI Explorer.
