Dbareudp.rst11 The Bareudp tunnel module provides a generic L3 encapsulation support for
12 tunnelling different L3 protocols like MPLS, IP, NSH etc. inside a UDP tunnel.
30 This creates a bareudp tunnel device which tunnels L3 traffic with ethertype
44 For an IPv4 tunnel the multiproto mode allows the tunnel to also handle

Dgtp.rst12 of a GTP tunnel endpoint.
17 GTP is the Generic Tunnel Protocol, which is a 3GPP protocol used for
24 such a tunnel between that external data network and the phone. The
25 tunnel endpoints thus reside on the phone and in the gateway. All
