[ovs-discuss] MPLS and ovs-ofctl

[Vasu Dasari]

Hi Andy,

I tried this command on OVS 1.11. And the command was successful.

Here the following command is looking for a specific srcmac, dstmac, ether
type and vlan id to push a mpls label on top of it.

ovs-ofctl add-flow br0
in_port=1,dl_type=0x0800,dl_src=00:00:00:00:01:01,dl_dst=00:00:00:00:01:02,dl_vlan=1,actions=push_mpls:0x8847,set_field:100-\>mpls_label,output:2.

Probably this could get you started.

Regards,
-Vasu
