[ovs-dev] [PATCH 5/7] userspace: L3 tunnel support for GRE and LISP
Jan Scheurich
jan.scheurich at ericsson.com
Fri Feb 3 10:40:34 UTC 2017
Add a boolean "layer3" configuration option for tunnel vports.
The layer3 option defaults to false for all ports except LISP.
GRE ports accept both true and false for "layer3".
A tunnel vport configured with layer3=true receives L3 packets.
which are then converted to Ethernet packets by pushing a dummy
Ethernet heder at the ingress of the OpenFlow pipeline. The
Ethernet header of a packet is stripped before sending to a
layer3 tunnel vport.
Presently a single GRE vport cannot carry both L2 and L3 packets.
But it is possible to create two GRE vports representing the same
GRE tunel, one with layer3=false, the other with layer3=true.
L2 packet from the tunnel are received on the first vport, L3
packets on the second. The controller must send packets to the
layer3 GRE vport to tunnel them without their Ethernet header.
Units tests have been added to check the L3 tunnel handling.
