Configure IP Multicast over Fabric Connect Globally

Use this procedure to globally enable IP Multicast over Fabric Connect 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. There is no need to enable IP Multicast over Fabric Connect on the Backbone Core Bridges (BCBs).

You must configure IP Multicast over Fabric Connect at the global level, and then enable it on the service option or options you choose.IP Multicast over Fabric Connect uses I-SIDs that start at 16,000,000 and above. The device displays an error message if the Layer 2 and Layer 3 I-SIDs are within this range and the system does not enable IP Multicast over Fabric Connect.

IP Multicast over Fabric Connect uses I-SIDs that start at 16,000,000 and above. The device displays an error message if the Layer 2 and Layer 3 I-SIDs are within this range and the system does not enable IP Multicast over Fabric Connect.

Note

Note

You must enable IP multicast over Fabric Connect globally on all DvR enabled nodes (Controllers and Leaf nodes) in a DvR domain.

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.

Procedure

  1. In the navigation pane, expand Configuration > IS-IS > SPBM to determine if any I-SIDs are within the default range reserved for multicast..
  2. Select the I-SID tab to determine if the I-SIDs are within the default range reserved for multicast.
  3. In the navigation pane, expand Configuration > IS-IS > SPBM.
  4. Select the SPBM tab.
  5. If you want to enable multicast on an SPBM instance that already exists, in the Mcast column in the table, select enable.
  6. If you want to enable multicast on an SPBM instance that does not yet exit, select Insert.
  7. In the Mcast box, select enable to enable IP Multicast over Fabric Connect globally.
  8. Select Insert.
  9. Select Apply.

SPBM Field Descriptions
