An engineer is extending EPG connectivity to an external network. The external network houses the Layer 3 gateway and other end hosts. Which ACI bridge domain configuration should be used?
A.
Forwarding: Custom
L2 Unknown Unicast: Hardware Proxy L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Enabled
B.
Forwarding: Custom
L2 Unknown Unicast: Flood
L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Enabled
C.
Forwarding: Custom
L2 Unknown Unicast: Hardware Proxy L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Disabled
D.
Forwarding: Custom
L2 Unknown Unicast: Flood
L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Disabled
When extending EPG connectivity to an external network that houses the Layer 3 gateway and other end hosts, the ACI bridge domain configuration should use Forwarding: Custom, L2 Unknown Unicast: Hardware Proxy, L3 Unknown Multicast Flooding: Flood, Multi Destination Flooding: Flood in BD, and ARP Flooding: Enabled23. This configuration ensures that unknown unicast traffic is handled efficiently while still allowing ARP flooding, which is necessary for the ACI fabric to learn about endpoints on the external network23.
