  2. Run the efa tenant service bgp peer-group delete command.
    If the deletion fails, run the efa tenant service bgp peer-group delete command with force option.
    (efa:root)root@node-2:~# efa tenant service bgp peer-group delete --name ten1bgppg1 --tenant ten1
BgpService deletion Failed:
Error :  PeerGroup pg1 has dynamic Neighbor 10.20.30.0/23 configured on Device 10.20.246.16


(efa:root)root@node-2:~# efa tenant service bgp peer-group delete --name ten1bgppg1 --tenant ten1 –force

Bgp service peer-group delete with "force" option will delete the device configuration corresponding to the bgp and also deletes the bgp record from the application. Do you want to proceed (Y/N): Y
