Thanks Michael, i have applied the WA but i have seen one strange thing that BFD and description of the fabric interface is not pushed by EFA while doing device update

it has only ip address and both the side and underlay bgp is up but no bfd , like other fabric interfaces . any reason ?

"efa inventory device update" does not push any configuration, it simply updates XCO with the current status of the Fabric device

The only time configuration is pushed is with a DRC or fabric configure.

DRC:

"efa inventory drift-reconcile execute --ip [IP_ADDRESS] --reconcile"

- If the --reconcile flag is not used, no config is changed, XCO simply prepares a list of drifted config you can view in "efa inventory drift-reconcile detail --uuid"

Fabric Configure:

"efa fabric configure --name [FABRIC_NAME]"

I would run a DRC.
