Hi,

I am trying to implement a functionality, where in if user specifies port
through which a VxLAN encapsulated packet can be sent out, then use that
port rather than going through routing procedure.

ovs-vsctl add-port br0 at_vxlan_fp1 -- \
        set int at_vxlan_fp1 type=vxlan \
        options:remote_ip=172.32.2.1 options:local_ip=172.32.2.100 \
        options:dst_mac=00:00:00:00:01:02 options:src_mac=00:00:00:00:01:01
\
        options:out_port=1

This would create a fully specified tunnel port, it includes all L2 and L3
parameters needed to create encapsulated frame. This kind of syntax would
mimic what is supported by off the shelf hardware like Broadcom. I also
noticed that pica8's Openflow switch supports this kind of syntax as
well (Configuring
VXLAN <https://docs.pica8.com/display/PICOS2111cg/Configuring+VXLAN>)

And the user could create flows of this sort to transport user packets with
VxLAN payload:

ovs-ofctl add-flow br0 priority=1,in_port=ovs-ap0,actions=at_vxlan_fp1
ovs-ofctl add-flow br0 priority=1,in_port=at_vxlan_fp1,actions=ovs-ap0


I have initiated a discussion for this kind of request in June, 2019
at, ovs-discuss
thread
<https://mail.openvswitch.org/pipermail/ovs-discuss/2019-June/048754.html>.
And would like to use this thread for design and any other comments.


Please let me know what you think.


Thanks

-Vasu
