Re: [ovs-discuss] [SFC NSH] Update "eth_dst" for original packet after decap nsh encapsulation packet.
I don't think OVS supports this kind of encapsulation.

Re: [ovs-discuss] [SFC NSH] Update "eth_dst" for original packet after decap nsh encapsulation packet.
Hi Ben, thank for your I am sorry because I didn't show the encapsulation command. In this case, original packet is encapsulated 2 times, with nsh and ethernet headers. Here is the flow: table=0, n_packets=0, n_bytes=0, priority=30,tcp,in_port="tap09d8de0e-20",nw_src=10.10.0.111,nw_dst= 10.10.0.0/24,tp_dst=80 actions=encap(nsh),set_field:0x33->nsh_spi,set_field:255->nsh_si,encap(ethernet),set_field:fa:16:3e:05:3a:12->eth_dst,resubmit(,5) As I known, after using decap() 2 times, I can get the original packet. So, I can update eth_dst to it.

It looks to me that the first decap removes the NSH header and the second decap removes the Ethernet header. At that point, there's no Ethernet destination field to set, so the error seems reasonable. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
