Overview

This interface reference guide describes the enhancements that support additional
protocols for access and core network traffic. This includes supporting additional
tunnel types (both access and core), core network forwarding rules and new
networking protocols (both access and core).
On the core network, UE traffic from APs along with next-hop destinations based
on forwarding policy supports:
• L2oGRE, which establishes a GRE tunnel to the core network forwarding
gateway along with an Ethernet payload. That is, the client's MAC is available
to the next hop gateway. In addition, data plane supports in sending non-
tunneled packets to the core network with optional VLAN or QinQ tags.
• PMIP tunneling is between the SCG (MAG) and LMA and is per session. The
tunneling to carry the payload is IPv4 over GRE over IPv4 type.
On the access network, UE traffic from 3rd Party APs is sent to the data plane via
an L2oGRE tunnel, or alternatively a QinQ tunnel configuration on the access
network. This is in addition to QinQ packets on the access network. The configu-
ration is per zone with specifications of the IP range of the connecting tunnel
endpoint. The tunnel is accepted and the UE packet is accepted (based on per zone
authentication settings) as long as the IP address of the GRE tunnel endpoint is
within that range.
Figure 1 shows the tunneling interface and its various tunneling interfaces.
