L2oGRE with TTG PDG Profile with 802.1x
Authentication
This network protocol supports authentication of UE tunnel traffic from 3rd party
APs using 802.1X, via L2oGRE tunnels. 3rd party AP UE's using 802.1X authenti-
cation is already supported with QinQ access and LBO core forwarding by config-
uring the TTG+PDG profile.
The UE authentication is similar to QinQ and LBO expects that the UE packet is
seen at the data plane from an L2oGRE tunnel. This means that the L2oGRE and
LBO path is already supported for the parameter auth_type.
