Users need to explicitly enable centralized routing at the tenant VRF level to override the default distributed routing behaviour.
Hence a given tenant can have multiple VRFs with some VRFs operating in distributed routing mode and some VRFs operating in centralized routing mode.
VRF Create
efa tenant vrf create --name <vrf-name> --tenant <tenant-name>
--routing-type {centralized | distributed}
--centralized-router <list-of-border-leaf-routers>
Example
efa tenant vrf create --name VRF1 --tenant tenant1
--routing-type centralized --centralized-router BL1-IP,BL2-IP
