EVPN - Symmetric IRB & Super Fabrics
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.
Concepts and Terminology Used in Super Fabrics
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
•EVPN – VXLAN Ethernet VPN
•VRF – Virtual Routing and Forwarding
•VNI – VXLAN Network Identifier
