Hi,
I'm currently experimenting with SDN. In particular, I'm running the latest HP VAN SDN controller (192.168.0.102) with Mininet. Pings for mininet hosts seem to work only when I specify the 'protocols=OpenFlow10'. Leaving default or using 'protocols=OpenFlow13', the pings fail.
sdn@mininet:~$ sudo mn --controller=remote,ip=192.168.0.102 --switch ovs,protocols=OpenFlow10

I have tried with the ODL controller (192.168.0.101) and the ping works in Mininet for both OF1.0 and OF1.3.

Just wondering why pings are failing with the HP VAN SDN when specifying OF1.3 in Mininet. Any help much appreciated.
