This allows auto RT to be used even if the Clos leaf-spine design has separate ASN for each leaf node. Configure this command only when all the VTEPs are OS10 switches. 11. Configure VLT. ● Configure a VLTi VLAN for the virtual network.

This VLAN interface is unnumbered interface and is used for iBGP peering with the other VLT peer.
