Super Fabric


A Super Fabric expands the maximum number of switches from 32 to 140 using four pods. We use the concept of Pods, with each pod containing up to a maximum of 32 switches.

Terminology


Local – A subnet is deemed Local to a POD if it is only configured on that POD.

Remote – A subnet is deemed Remote if it is not LOCAL on that POD.

Stretched – A subnet is deemed Stretched if it is present on two or more PODs.

IRB – Integrated Routing and Bridging

EVPNVXLAN Ethernet VPN

VRF – Virtual Routing and Forwarding

VNI – VXLAN Network Identifier
