BGP Auto-pering Simple Leaf/Spine Example

The following example shows a simple leaf/spine topology with users on VLAN (Virtual LAN)s, red and blue, noted as 1 and 2.

Note

Note

An Advanced Edge license must be installed on all devices.

The following commands reserve 64 VLANs, which is the maximum. It is recommended to reserve more than needed, so you can add links without recreating the auto-peering network.

Devices labeled with router IDs 10.255.x.y:
