Overview

Explains a routed overlay network in EVPN multihoming mode. This chapter also explains how to configure routed overlay networks, along with configuration examples.

Routed overlay network overview

Explains the structured VLAN-to-subnet IP addressing plan used in multilayer campus networks and its integration with underlay and overlay routing.

Understanding routed overlay networks

Routed overlay networks use BGP EVPN VXLAN technology to create scalable, flexible Layer 2 and Layer 3 campus fabrics. These networks enable efficient multihoming, streamlined route management, and support for robust redundancy and network segmentation.

Configure routed overlay networks

Lists the tasks to configure a routed overlay network.

Verify the routed overlay network configuration

Provides examples of commands and their typical outputs to verify the routed overlay network configuration and the states of the VTEPs.

Reference routed overlay network configuration
