Hi,
Im having some issues to send a packet out message between 2 ovs. Im have 3
PCs. 2 of them act like an ovs and the third one has the Ryu controller. Im
have a vlan (vid=44) por signal traffic between both ovs and the controller
and a vlan (vid=10) just for transport between both ovs. I also have the 3
PCs physically connected by a Cisco Catalyst 2960 switch. Im figuring out
how to send a packet out from one ovs (172.16.10.10) to the other ovs
(172.16.10.20) without receiving a packet in message first. Now im sending
the packet out in the switch features handler as follows:
@set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER)
def switch_features_handler(self, ev):
msg = ev.msg
datapath = msg.datapath
ofproto = datapath.ofproto
parser = datapath.ofproto_parser
match_miss = parser.OFPMatch()
actions_miss = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER,
ofproto.OFPCML_NO_BUFFER)]
self.add_flow(datapath, 0, match_miss, actions_miss)
match_2 = parser.OFPMatch(in_port=1, eth_type=0x800,
ipv4_dst='172.16.10.20')
actions_out = [parser.OFPActionOutput(port=1)]
self.add_flow(datapath, 1, match_2, actions_out)
#I send the packet out just from one ovs:
if msg.datapath_id == 233669375027733:
p = packet.Packet()
ip = ipv4.ipv4(src='172.16.10.10', dst='172.16.10.20')
#v_lan = vlan.vlan(vid=10)
p.add_protocol(ip)
#p.add_protocol(v_lan)
p.serialize()
match_out = parser.OFPMatch(in_port=1)
out = parser.OFPPacketOut(datapath=msg.datapath,
buffer_id=ofproto.OFP_NO_BUFFER,
match=match_out, actions=actions_out,
data=p.data)
datapath.send_msg(out)
