hi, Actually the issue is according to openflow 1.0 spec when i use *ovs-ofctl add-flows br0 "dl_type=0x0800 nw_proto=1 nw_dst=10.0.3.4 nw_src= 10.1.3.2/8 actions=1" * *ovs-dump-flows br0 should give follwing output * cookie=0x0, duration=21.265s, table=0, n_packets=0, n_bytes=0, icmp,nw_src=10.0.3.4*,nw_dst=10.1.3.0/8 *actions=output:1 * *that is the least significant 8 bits should be wildcarded.
But in openvswitch the ovs-dump-flows br0 give me following output cookie=0x0, duration=21.265s, table=0, n_packets=0, n_bytes=0, icmp,nw_src=10.0.3.4,*nw_dst=10.0.0.0/8* actions=output:1 this means least significant 24 bits are wildcarded. In openvswitch code it is shown that CIDR masks are supported for IP address, which is not openflow 1.0 compliant. I get the same result when i look at output of ovs-ofctl specking openflow.
