Multiple VLAN Based tenants cannot share the same VLAN, considering the multiple tenants cannot share the same VNI.
Multiple BD Based tenants can share the same VLAN, as the VLANs from each tenant will be mapped to a unique BD and further a unique VNI.
EFA supports multi tenancy by allowing multiple tenants to have overlapping ctags and non-overlapping L2VNI. A tenant ctag will get a unique L2VNI and a unique network allocated in the fabric
The following example shows a multi tenancy configuration.
