Thanks Murphy. That was extremely helpful.

I am assuming that by 10.10.23.40/2, you don't intend the CIDR meaning, and in fact mean that you want two bits to be wildcarded. Try this: wildcard = (wildcard& ~OFPFW_NW_DST_MASK) | (wild_bits<< OFPFW_NW_DST_SHIFT); .. where wild_bits is between 0 and 32 inclusive (in your case, it should be 2). Hope that helps. -- Murphy On Jan 9, 2012, at 10:24 AM, Theophlius Benson wrote:Good Morning, I am trying to install rules into switches to match ip prefixes. For example 10.10.23.40/2. However, the rules i install endup looking like this: 0.0.0.0/2. I'm sure that I'm installing these rules incorrectly. Here is a fragment of the code that sets the matching criteria. wildcard = (~OFPFW_NW_DST_ALL& (OFPFW_NW_DST_MASK<< dstmask)) | wildcard; ofm->match.wildcards = htonl(wildcard); ofm->match.nw_dst=htonl(dstip); I Can include more fragments of the code if you will find it helpful.
