Encapsulation Normalization

Traffic within the fabric is encapsulated as VXLAN. External VLAN/VXLAN/NVGRE tags are mapped at ingress to an internal VXLAN tag.

Forwarding is not limited to or constrained by the encapsulation type or encapsulation overlay network. External identifiers are localized to the leaf or leaf port, which allows reuse or translation if required. A bridge domain forwarding policy can be defined to provide standard VLAN behavior where required.
