Multi-Fabric EVPN Overview

The Multi-Fabric Fabric is a group of AOS-CX Switches that are part of the BGP-EVPN VXLAN overlay. The overlay fabric is created by configuring VXLAN tunnels between stub and edge Switches. This is in context to Aruba Central NetConductor. EVPN in NetConductorallows you to build independent fabric for administrative construct allowing to scale for large, geo-dispersed deployments. Independent fabric are inter-connected together across metro Ethernet Ethernet is a network protocol for data transmission over LAN. or IP Network. Multi-Fabric EVPN allows to extend segmentation (VLANs Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN., VRFs, Roles) with consistent Group-based Policy. Fabric inter-connectivity requires network to support higher MTU Maximum Transmission Unit. MTU is the largest size packet or frame specified in octets (eight-bit bytes) that can be sent in networks such as the Internet. (≥ 1550 bytes) to accommodate VXLAN Virtual Extensible LAN creates virtual networks overlaid on a physical network. encapsulation between sites. Maximum of 32 Fabrics can be interconnected horizontally in a Multi-LayerFabric Design.
