Exclusion of VLANs and Bridge from Cluster Instance

XCO excludes VLANs and bridge domains used in the Layer 3 hand-off (toward the external gateway) endpoint group from the cluster instance by configuring member vlan remove <vlan-range> and member bridge-domain remove <bd-range> under the cluster instance.

During XCO upgrade, XCO marks all the VLANs and Bridge Domains (BD) 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, XCO pushes member vlan remove <vlan-range> and member bridge-domain remove <bd-range> configuration under the cluster.
