This feature adds support for mapping a UE to a VPLS instance based on configuration. The mapping is explicitly created by assigning a VPLS instance to an SSID that the UE is connected to. The SSID is represented by the dot1q tag in the received Layer 2 frames from the UE. A VPLS instance is configured per vlan-range on wlan-gw group-interface (as shown in Figure: Standalone WLAN-GW ). This feature therefore enables Layer 2 wholesale, where traffic from all UEs on an SSID is transparently forwarded into the corresponding VPLS instance associated with the retail ISP. UE authentication, address assignment, Layer 3 classification and QOS are managed by the retail provider terminating the subscriber. There is no local-switching on the WLAN-GW providing the wholesale service. When a VPLS instance is configured under a VLAN-range, an internal SAP is implicitly created in the VPLS instance between each ISA and corresponding carrier IOM in the WLAN-GW group. The internal SAP is associated with an implicitly created SHG to constrain broadcast and multicast traffic received from UEs, such that it is not forwarded back on the SAP. Layer 2 wholesale and Layer 3 termination are possible simultaneously on same wlan-gw interface, because Layer 2 wholesale or Layer 3 termination is a per SSID decision. UE state on the ISA is removed when the UE MAC in the VPLS instance ages out based on local-age configured under VPLS service.
A vpls-sap-template command (described in the 7450 ESS, 7750 SR, 7950 XRS, and VSR Layer 2 Services and EVPN Guide) can be defined under config>service>template and associated with the VPLS service for Layer 2 wholesale via config>service>vpls>wlan-gw>sap-template command. Ingress and egress filter and QoS specified in the vpls-sap-template for the VPLS service is applied to the implicitly created internal SAP (between ISA and carrier IOM) in the VPLS service.
