What is the purpose of enabling ARP flooding when VMs are migrated from a pre-existing network to Cisco ACI and their gateways remain configured in the legacy setup?
A.
to avoid endpoint flapping between the legacy network and the ACI fabric
B.
to prevent VMs from communicating with physical servers within the ACI fabric
C.
to allow communication between VMs and silent hosts
D.
to allow VMs to communicate with devices outside of their subnet
The gateways are outside of ACI and VMs are inside of ACI. If ARP flooding is not enabled VMs are not going to be able to resolve the GW MAC when needed.
A. to avoid endpoint flapping between the legacy network and the ACI fabric
/ only A makes sense, other options relate to allowing/denying which are contracts
