Deployment Guide

27 VCF on VxRail Multirack Deployment using BGP EVPN
6 Configure and verify the underlay network
6.1 Configure leaf switch underlay networking
This chapter details the configuration for S5248F-ON switch with the hostname sfo01-Leaf01a, shown as the
left switch in Figure 17. Virtual networks 1641 and 3939 are shown in the diagram as an example. All the
required virtual networks are created during the switch configuration. Configuration differences for Leaf switch
1b, 2a, and 2b are noted in Section 5.8. These commands should be entered in the order shown.
Note: This deployment uses four leaf switches. All four leaf switch configuration files are provided as
annotated text file attachments to this .pdf. Section 1.7 describes how to access .pdf attachments. All
switches start at their factory default settings per Section 5.7.
