DRAG DROP

A leaf receives unicast traffic that is destined to an unknown source, and spine proxy is enabled in the corresponding bridge domain. Drag and drop the Cisco ACI forwarding operations from the left into the order the operation occurs on the right.

Select and Place:

DRAG DROP

Refer to the exhibit. Drag and drop the subnets and flags from the left into the External Network Instance Profile policies on the right to create a setup that advertises only 10.10.0.0/24 and 10.10.1.0/24 prefixes in VRF1 and establishes connectivity between VRFs. Not all options are used.
