Abstract
Importing of a UE address into a VRF of perimeter equipment is facilitate by receiving a VPN update from the perimeter equipment including a route target of the perimeter equipment and a gNodeB address. In addition, session information is obtained by intercepting traffic between the UE address and a UPF. The session information including the UE address and address of a gNodeB to which the UE is connected. By matching the gNodeB addresses from the VPN update and the session information, the route target of the perimeter equipment to which the UE is connected may be determined. The UE address may then be imported exclusively into the VRF of the perimeter equipment.
