BGP EVPN VXLAN Scalability Guide

Scale and Performance Capabilities for BGP EVPN VXLAN on Cisco Catalyst 9300 Series Switches

This section provides information about the platform capabilities and the scale values for various components of a BGP EVPN VXLAN fabric. The numbers in the following table depend on the ternary content addressable memory (TCAM) scale. Use the SDM configuration templates to adjust the Layer 2 and Layer 3 TCAM forwarding table sizes based on the platform positioning. For more information, see Configuring SDM Templates module of the System Management Configuration Guide for the applicable release.

The scale values listed here are validated with a unidimensional configuration. The values provided in these tables focus on the scalability of one particular feature at a time.

The scale values are applicable to all the models, unless otherwise stated.
