Hi, Llorente
For historical reasons, REST API cannot use full of fields defined in
ofproto/*.py.
The list of match fields REST API can use is shown here:
http://ryu.readthedocs.io/en/latest/app/ofctl_rest.html#description-of-match-and-actions
To use "tun_ipv4_src" and "tun_ipv4_dst" via REST API,
adding fields in this list might be good:
https://github.com/osrg/ryu/blob/6dfda4a227c493c1aed6c468d763650d21d5acce/ryu/lib/ofctl_v1_3.py#L195
Thanks,
Fujimoto

Hello community!
I am trying to use Ryu REST API to insert a flow in an OpenvSwitch
datapath. Unfortunately, I have run into problems with the fields
tun_ipv4_src and tun_ipv4_dst. However, if I add the intended flow via
ovs-ofctl, then I can then fetch it correctly through the Ryu REST API.
The ovs-ofctl command is the following:
# ovs-ofctl add-flow -O OpenFlow13 br-test0
"table=0,priority=10,in_port=100,ip,nw_src=192.168.0.100,nw_dst=172.16.0.1
actions=set_field:100.64.1.130->tun_src,set_field:100.64.2.130->tun_dst,set_field:5->tun_id,output:101"
Is there any way around this issue? I took a look at the ofctl_rest.py
but couldn't figure out myself how to modify the parser so it accepts
Nicira fields.
Thank you!
Jesus
