L2Ogre And Bridge - Ruckus Wireless SmartCell Gateway 200 Reference Manual

3rd Party Access Network Protocol
Access Network
For 3rd party APs, if the attribute, src_ip address is within the range, the tunnel is
automatically created. It does not require a setup. The AP table is for 3rd party AP
only and entries are timed-out periodically based on the in-activity. The complete
UE Ethernet packet is passed to the forward packet module, which is responsible
for forwarding the packet based on the rules and service policies.
NOTE: For information on how to configure L2oGRE, refer to the SmartCell
Gateway 200 Administrator Guide (PDF) or the SmartCell Gateway 200 Online Help,
which is accessible from the SCG Web interface.

L2oGRE and Bridge

In the user interface, the administrator user configures the access network as
L2oGRE and the core network as Bridge.
UE packets from the access network are sent to the data plane inside a layer 2
GRE tunnel. L2oGRE packets with outer source IP within the configured ranges are
accepted. The fwd_policy in this configuration is to bridge the inner UE packet to
the core-side network with 0, 1 or 2 VLAN tags as configured. See Figure 12 for the
schematic flow of 3rd party APs using L2oGRE and Bridge.
