aci multisite intersubnet across sites steps
The only difference is that the source endpoint will always resolve the ARP request with the local leaf node to which it connects and send the data packet destined for the remote endpoint to it
The leaf node will then need to deliver the traffic to the destination endpoint and, assuming that EP2 is not known on the leaf node, the traffic will be sent to the proxy VTEP address on the local spine nodes
EP2 is not known in the source Site 1: the local spine will perform a lookup, and because EP2 is unknown, traffic will be dropped.
EP2 is known in source Site 1: In this case, the local spine node will encapsulate traffic to the DP-ETEP address that identifies the remote site to which EP2 belongs, and the packet will eventually be received by the destination endpoint
