IP multicast over Fabric Connect

Provisioning IP multicast over Fabric Connect is as simple as enabling multicast over Fabric

Connect on the BEBs. You do not need to enable IP multicast over Fabric Connect on the BCBs.

For Layer 2 VSN using IP multicast over Fabric Connect, configure Internet Group Management

Protocol (IGMP) snooping on the VLAN that represents the Layer 2 VSN.

For Layer 3 VSNs using IP multicast over Fabric Connect, configure the Layer 3 VSN as a multicast

VSN, and then enable IP multicast over Fabric Connect on each VLAN within the VRF to which IP

multicast senders and receivers attach.

For IP shortcuts using IP multicast over Fabric Connect, enable IP multicast over Fabric Connect on

each of the VLANs within the Global Routing Table (GRT) that need to support IP multicast traffic.

Implementation options

The SPBM architecture is architecturally simple and easy to provision, but it is not just for simple

networks. SPBM supports multiple implementation options within the same network to meet the

demands of the most complex network configurations. The following figure shows how SPBM

supports multiple campus networks as well as multiple data centers.

Figure 44: SPBM support for campus and data center architecture

Within the SPBM architecture, you can implement multiple options. The following figure shows all

the options that SPBM supports.
