7 Example 2: Layer 3 with Dell EMC leaf and spine switches
using eBGP
This section provides eBGP configuration examples to build the layer 3 leaf-spine topology shown in Figure
13. Dell EMC Networking S4148F-ON and S4248FB-ON switches are used at the leaf layer and Dell EMC
Networking Z9100-ON switches are used at the spine layer. While the S4148F-ON configuration is shown in
this section, the configuration details for the S4248FB-ON switches are attached.
Note: The BGP ASNs and IP addresses defined in Section 5 are used here.

Example 2: Layer 3 leaf-spine topology
Note: All switch configuration files for the topology in Figure 13 are contained in the attachment named
Example2_config_files.pdf. The files may be edited as needed in a plain text editor and commands pasted
directly into switch consoles. Dell EMC Networking switches start at their factory default settings per
Appendix A.
