From all the ACI Multi-Site documents I have read, the use cases are mostly: L2 Stretch within same VRF; L3 Communication within same VRF; L3 inter-VRF communication within same Tenant. What about L3 communication between Tenants?
Hypothetically assuming there is only one WAN link between ACI sites as the ISN. Each site does have local L3Outs to Internet. I setup the Tenat 1/VRF 1 in site 1 and Tenant 2/VRF 2 in site 2. With the Multi-Site solution, would Endpoints under Tenant 1/VRF 1 in site 1 be able to communicate with Endpoints under Tenant 2/VRF 2 in Site 2 using overlay over the ISN?
