Beryllium SFCOFL2 Tutorial - Error in SfcL2RspProcessor (Invalid range)

Hello everyone!

I 'm trying to deploy the *SFCOFL2 Tutorial* which is placed in the user-guide of berrylium.

I have made it with Lithium odl and I could take the correct flows using these commands on mininet VM:

sudo ovs-ofctl -O OpenFlow13 dump-flows s2
sudo ovs-ofctl -O OpenFlow13 dump-flows s3

Now, I 'm using the stable/beryllium branch of sfc project.

I 'm creating the same topology in the mininet VM:
*sudo mn --topo linear,4 --mac --controller remote,ip=<ip>,port=<port> --switch ovsk,protocols=OpenFlow13*

I have fixed my json data to create correctly the SFFs with their related SFs DPL and I 'm seeing them to the SFC UI.

The problem is when I create the RSP and the random path-id is bigger than 63!!

If randomly the path-id is for example 40 the flows are created succesfuly in the s2 and s3 bridges, but if the path-id is 174 or something bigger than 63 the following exception is appeared:
