Enable IP Multicast over Fabric Connect Globally
Before you begin
You must configure the required SPBM and IS-IS infrastructure, which includes the creation of SPBM B-VLANs.
You must create the customer VLANs (C-VLANs) and add slots/ports.
You must add IST slot/ports to the C-VLAN for an SMLT topology.
About this task
Use this procedure to enable IP Multicast over Fabric Connect globally on the Backbone Edge Bridges (BEBs) that directly, or indirectly (using Layer 2 switches), connect to IP multicast senders or receivers. By default, IP Multicast over Fabric Connect is disabled. You do not need to enable IP Multicast over Fabric Connect on the Backbone Core Bridges (BCBs).
You must configure IP Multicast over Fabric Connect globally, and then enable it on the service option or options you choose.
You must enable IP multicast over Fabric Connect globally on all DvR enabled nodes (Controllers and Leaf nodes) in a DvR domain.
Note
IP Multicast over Fabric Connect uses I-SIDs starting at 16,000,000 and above. If Layer 2 or Layer 3 I-SIDs are in this range, the system displays an error message and the switch does not enable IP Multicast over Fabric Connect.
