From the NX-OS CLI, we can see that Protocol Independent Multicast(PIM) is enabled for the VRF:
apic1# sh run tenant TenantA# Command: show running-config tenant TenantA tenant TenantA vrf context TenantA_VRF ip pim exit bridge-domain TenantA-BD vrf member TenantA_VRF exit application TenantA_AP1 epg TenantA_EPG1 bridge-domain member TenantA-BD exit exit interface bridge-domain TenantA-BD ip address 10.0.0.1/24 secondary ip address 10.2.20.1/24 secondary scope public ipv6 address 2001:abcd:abcd::1001/64 exit exitapic1#
So maybe I was a little overenthusiastic about the simplicity that ACI brings to traditionally complex tasks, but this is not without reason. ACI is very easy to learn.
We have not quite finished with multicast, ...
