How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?

A.

For the specific bridge domain, all spines forward the broadcast frames to IPN routers

Broadcast frames are forwarded inside the pod and across the IPN using the multicast
address that is associated to the bridge domain

C.

Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports

D.

 Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure
