[Ryu-devel] unsupported version 0x1. If possible, set the switch to use one of the versions [4] when mininet connects to RYU

Hi Karthik,

You are trying to use OFv1.3 application on top of Ryu against mininet
which is running OFv1.0 which is resulting in the error.

Try using OFv1.0 application on top of Ryu to prevent the error.

Regards,

Vinay Pai B.H.
