+> [!NOTE]
+> Connectivity configuration allows virtual networks with overlapping IP spaces within the same connected group, but communication to an overlapped IP address is dropped. In addition, when a connected group’s VNet is peered with an external VNet (a VNet not in the connected group) that has overlapping address spaces, these overlapping address spaces become inaccessible within the connected group. Traffic from the peered VNet to the overlapping address spaces is routed to the external VNet, while traffic from other VNets in the connected group to the overlapping address spaces is dropped. Logs will show a "Warning" level, with the `TargetResourceIds` field indicating the IDs of VNets with overlapping address spaces and a `message` indicating that either complete or partial address spaces are inaccessible due to overlapping addresses.
