EFA excludes the VLANs/BDs used in l3-hand-off (towards external-gateway) EPG from cluster instance by configuring member vlan remove <vlan-range> and member bridge-domain remove <bd-range> under the cluster instance.
During EFA upgrade, EFA marks all the VLANs/BDs used in l3-hand-off EPGs with the intended member vlan remove <vlan-range> and member bridge-domain remove <bd-range> configuration and shows as configuration drift. On reconciliation of the drift, EFA pushes member vlan remove <vlan-range> and member bridge-domain remove <bd-range> configuration under the cluster.
