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
