Chapter 1. Verified Scalability for Cisco Programmable Fabric with VXLAN BGP EVPN

This chapter contains the following sections:

- Overview of Verified Scalability

- Verified System-Level Scalability

- Verified Scalability for Leaf Switch

- Verified Scalability for Border Leaf Switch

Overview of Verified Scalability

This document lists the verified scalability limits for Cisco Programmable Fabric with virtual extensible LAN (VXLAN) Border Gateway Protocol Ethernet VPN (BGP EVPN).

In the tables provided in this topic, the Verified Limit column lists the verified scaling capabilities, with all the listed features enabled at the same time. The numbers listed here exceed those used by most customers in their topologies. The scale numbers listed here are not the maximum verified values if each feature is viewed in isolation.

The scale numbers in the table are the absolute maximum values that are supported by Cisco NX-OS release software for VXLAN with BGP EVPN control plane.

For information about the list of verified maximum scale capabilities tested for the corresponding features individually, refer to the respective Cisco Nexus 5600 Switches, Cisco Nexus 7000 Series Switches, Cisco Nexus 7700 Switches, and Cisco Nexus 9000 Series Switches scalability guides.

Note

The scale numbers for the Cisco Nexus 9000 Series Switches as part of Cisco Programmable Fabric will be available in a subsequent release of the Verified Scalability Guide.

Verified System-Level Scalability

This table lists the verified system-level scalability for Cisco Programmable Fabric with VXLAN BGP EVPN deployment.

[3] Cisco Nexus 7000 Series and Cisco Nexus 7700 F3 module supports 64,000 total TCAM lines that can be divided between IPv4 (1 TCAM line) and IPv6 (2 TCAM lines).

[4] VXLAN extended VLANs are exempt from IGMP snooping. (IGMP snooping is disabled.)
