[ovs-discuss] flow table question

[NS Srinivasa Murthy-B37840]

Hi,

When IP Addresses are to be specified as match fields, it is a pre requisite to include the match field OFPXMT_OFB_ETH_TYPE with a value of 0x800 (IP Protocol.)

Thanks

Subject: [ovs-discuss] flow table question

Hi, all

I am trying to insert two flows in table0 and table 1 separately. The first flow entry tries to pop the MPLS header and the second entry will match the rest of the packet, like dl_src,dl_dst, nw_src ... fields. The following are my flows:

table0:
 priority=0,mpls,in_port=2,
mpls_label=3 ,actions=pop_mpls:0x0800,load:0xe->OXM_OF_METADATA[],resubmit(,1)

table1:
priority=32786,tcp,metadata=0xe,in_port=2,dl_src=90:e2:ba:3d:c0:f8,dl_dst=90:e2:ba:28:e6:98,nw_src=10.0.3.4,nw_dst=10.0.1.4 actions=output:3

But the matching will fail if nw_src and nw_dst field are set in the table1 flow rule, while there is no problem if only ethernet header is set. Does anyone have any idea about what's going on here. I would appreciate your help a lot. Thanks.
