Hello guys,
I have a question related to the "options:remote_ip=flow" feature.
My config looks like this for one host:
[root@localhost ~]# ovs-vsctl show
e927ea5a-41d8-4bf5-9145-5be06e18bc9f
Bridge "br-eth0"
Port "br-eth0"
Interface "br-eth0"
type: internal
Port "eth0" (external interface)
Interface "eth0"
Bridge br-vnet
Port br-vnet
Interface br-vnet
type: internal
Port "vxlan1" (tunnel I use)
Interface "vxlan1"
type: vxlan
options: {key="10", remote_ip=flow}
Port "vnet0" (port for the virtual machine)
Interface "vnet0"
ovs_version: "1.12.90"
[root@localhost ~]#
If I set the "options:remote_ip=A.A.A.1" (the IP for host 2) everything
works just fine ARP requests from my VM, pings to the subnet, etc.
If I leave it like this, it doesn't work.
I followed some instructions that I could find by google-ing.
I know I need to set up flows to transmit and to receive, but I'm not
sure how.
Until now, for transmitting I used:
ovs-ofctl add-flow br-vnet
"in_port=1,actions=set_field:A.A.A.1->tun_dst,output:2"
(in_port = virtual network port, output = tunnel port)
I'm pretty sure this is right (feel free to correct me if I'm wrong).
And here's the ovs-ofctl output:
[root@localhost ~]# ovs-ofctl show br-vnet
OFPT_FEATURES_REPLY (xid=0x2): dpid:000096522ce20048

LOCAL(br-vnet): addr:96:52:2c:e2:00:48
config: 0
state: 0
speed: 0 Mbps now, 0 Mbps max
OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0
What other rules must I add in order for it to work?
And as an optional question: can I use "ovs-appctl ofproto/trace" to
test the entire environment from eth0 to vnet0 and viceversa?
Thanks in advance,
Andrei
