Description (partial)

Symptom:
This is an enhancement to add a fault if the Unicast VTEP IP address is missing from the Pod Connection Profile and remote leaf direct is enabled.

When the remote leaf direct feature is enabled, a Unicast VTEP is required in the Pod Connection Profile for the pod that the remote leaf is associated to. 

If this is missed during configuration, unicast traffic coming from the spines will be dropped on the remote leaf with drop vector "INFRA_ENCAP_SRC_TEP_MISS," assuming second generation+ platforms, because the leaf is expecting to receive traffic from the Unicast VTEP but one is not configured.

The MO class of the Unicast TEP entry is fvExtRoutableUcastConnP. The Unicast VTEP IP is in the attribute named "addr".

The MO class of fabric-wide settings is infraSetPol. The "enableRemoteLeafDirect" attribute determines whether remote leaf direct is enabled or not.
