You can use the following command to create a Clos fabric containing border-leaf devices, which can be used for centralized routing.
Tip
If any devices in a fabric are in "admin-down" state, use of the following commands in that same fabric will not add or delete devices in the fabric: efa fabric device add-bulk and efa fabric device remove.efa fabric create --name <fabric-name> --type clos
efa fabric device add-bulk --name <fabric-name>
--border-leaf <list-of-border-leaf-ip> --leaf <list-of-leaf-ip>
--spine <list-of-spine-ip>
efa fabric configure --name <fabric-name>
