OFP is sending wrong length for IPv6 Source Address Field

So while applications adding ipv6_src address, unused bits should be made zeros, before adding it to the config datastore.</p> <p> </p> <p>If we want to push a flow into config DS with an IPv6 address <b>i</b><b>pv6_src=fe80:0:0:0:f816:3eff:fe18:</b><b>bde2</b> with 64 bits masked, then it should be specified by making rest 64 bits as zeros like  <b>i</b><b>pv6_src=fe80::/64</b></p> Development Rank 0|i03f3r:
