The external switches start at their configuration shown in Configure external switches for L3 connections. This section covers the configuration changes for both external switches.
Configure interfaces
Configure the interfaces for L3 connections to the SmartFabric spine switches. Interfaces 1/1/53 and 1/1/54 are used in this example.
Enter configuration mode with the configure terminal command.
For each interface, add a description and take the port out of L2 mode with the no switchport command. Assign an IP address to each interface per Table 1.
Optionally, allow the forwarding of jumbo frames with the MTU 9216 command. As a best practice, flow control settings remain at their factory defaults as shown.

Configure BGP
Enter BGP configuration mode with the router bgp 65101 command. The external switches share the same ASN. For the router ID, use the address that was set for interface loopback0 in Configure external switches for L3 connections.
Configure the neighbor addresses per Table 1.
Configure the neighbor ASN. By default, all SmartFabric spine switches use 65012.
When the configuration is complete, exit configuration mode and save the configuration with the end and write memory commands.
