SR-MPLS handoff |
Prior to Cisco APIC Release 5.0(1), when setting up an ACI fabric connected to a data center provider edge (DC-PE) for a configuration with a multi-tenant network, you need multiple VRFs and a routing protocol for each VRF. You also need to dedicate an interface for each VRF, where the interface is either a physical interface or a logical interface. This configuration uses IP handoff and is typically called VRF-Lite. Beginning with Cisco APIC Release 5.0(1), you can now set up an ACI fabric connection with a DC-PE using segment routing (SR) Multiprotocol Label Switching (MPLS) handoff. SR is a better solution than other options, because other options such as VXLAN may not be a common technology in an SP Core, whereas SR is a much more common and mature solution for transport devices. |

Multicast filtering |
Beginning with Cisco APIC Release 5.0(1), the multicast filtering feature is now available, which allows you to filter multicast traffic from two directions: source filtering at the first-hop route and receiver filtering at the last-hop route. |
