cisco Catalyst 2960 — Configuration Example-Spine and Leaf Switches in the Same Autonomous System

Spine Switches in One Autonomous System and the Leaf Switches in a Different Autonomous System In this scenario, all the leaf switches are in a single autonomous system that is different from the autonomous system of the spine switches. The spine switches function as BGP route servers. iBGP is used to establish peering between the spine switches. eBGP is used to establish peering between the spine and leaf switches. See Configuration Example-Spine and Leaf Switches are in Different Autonomous Systems, on page 19 for a sample topology and configuration.

Spine Switches in One Autonomous System and Each Leaf Switch in a Different Autonomous System In this scenario, each leaf switch is in its own individual autonomous system that is different from the autonomous system of the spine switches. The spine switches function as BGP route servers. iBGP is used to establish peering between the spine switches. eBGP is used to establish peering between the spine and leaf switches. See Configuration Example-Each Leaf Switch in a Different Autonomous System, on page 37 for a sample topology and configuration.

Configuration Examples for Spine Switches in a BGP EVPN VXLAN Network This section provides configuration examples for spine switches for the different deployments of spine and leaf switches in a BGP EVPN VXLAN fabric. Configuration Example-Spine and Leaf Switches in the Same Autonomous System This section provides an example to show how spine switches are configured in a BGP EVPN VXLAN fabric using iBGP when the spine switches and leaf switches are in the same autonomous system. The example shows how to configure spine switches and verify the configuration for the topology shown below:
