[ovs-discuss] Reg. flow based tunneling

[P Balaji-B37839]

Hi Eswar,

You can try the below commands for flow based tunneling.

ovs-vsctl add-port br-int tun-port -- set Interface tun-port type=vxlan options:key=flow options:remote_ip=flow ofport_request=10 options:dst_port=5000

ovs-ofctl add-flow br-int "in_port=1 actions=set_field:10->tun_id,set_field:10.10.10.10->tun_dst,output:10"

ovs-ofctl add-flow br-int "in_port=10 actions=output:2"


Note: You can change the "dst_port" , "in_port" and "output" based on your requirement. Also if don't give dst_port it will be taken as default port while creating tunnelport in the switch.

Regards,
Balaji.P

Hi Jesse,
Thanks for the mail.

Please correct me if my below understanding is wrong.

VM port: 1, tunnel port:2 , needs to send broadcast flow to remote machines with remoteIP_1 and remoteIP_2
 # ovs-ofctl add-flow br-tun in_port=1  actions=set_field:<remoteIP-1> ->tun_dst, set_field:<vni>->tun_id, output:2
Can I add the flow as :
 # ovs-ofctl add-flow br-tun in_port=1  actions=set_field:<remoteIP-1> ->tun_dst, set_field:<vni>->tun_id,  set_field:<remoteIP-2> ->tun_dst, set_field:<vni>->tun_id output:2
I thought I can add 2 flows with in_port as 1 and actions with remote ips respectively. But if the flow matches to first entry it will not adhere to 2nd flow and doesn't send to remoteIP_2.

Thanks
Eswar

Yes, you can have multiple output actions.
