Can you send the output if you run with -v?
Hello,
I am trying to implement a monitoring protocol. For this I am
relying on the routing module. I have a simple setup involving three
openflow-enabled hardware switches. Below is the topology:
+----+ Vl 1+----+Vl 2 +----+
H1------| R1 |----------| R2 |----------| R3 |------H2
+----+ +----+ +----+
R1 and R2 share vlan 1 (ip 192.168.1.0/24) and R2 and R3 share vlan 2
(ip address 192.168.2.0/24). H1 (192.168.1.1) and H2 (192.168.2.1) are
end hosts.
Each vlan instance connects to the controller and is correctly picked
up by nox as it registers the correct number of datapaths and
switches. When I run, nox_core -i ptcp:2525 routing, I obtain the
following output:
a...@pcepatr39[src]$ sudo ./nox_core -i ptcp:2525 switch routing
[sudo] password for ash:
NOX 0.5.0~full~beta (nox_core), compiled Oct 13 2009 14:43:43

-> 00:00:2e:9a:ea:00:00:65 p:41)
So the links are correctly detected by the discovery module. But when
I attempt to ping H2 from H1. The only flow then I see setup is:
duration=11s, table_id=0, priority=65535, n_packets=9, n_bytes=540,
idle_timeout=60,hard_timeout=0,arp,in_port=48,dl_vlan=0xffff,dl_src=00:50:da:6e:ac:7f,
dl_dst=ff:ff:ff:ff:ff:ff,nw_src=0.0.0.0,nw_dst=0.0.0.0,nw_proto=0,tp_src=0,tp_dst=0,actions=FLOOD
And no other flows are setup and no messages are sent out by the
routing module. Am I missing something about the routing module? From
the manual it seems like it is supposed to setup flows on each router
from source till the destination.
I am running this on 3 hp 3500s, with nox 0.5.0 full.
Thanks for your help,
