Thank you Yamahata San
Ryu experts,
Adding some notes to clarify my problem at hand.
I am trying to setup a test bed to replicate the rest-router sample app
using 2 switches and 2 hosts *without* mininet. I am using a linux server
with multiple nic cards and open vSwitch and have created 2 switches (S1,
S2). Then using 2 laptops to emulate my client(H1) and server(H2) as
shown in the figure below (file attached as well):
H1 (10.0.0.2) --> (10.0.0.1) S1 (??) --- (??) S2 (20.0.0.1) -->
(20.0.0.2) H2
H1 default gw: 10.0.0.1
H2 default gw: 20.0.0.2
S1 default gw: S2 (192.168.0.20?)
S2 default gw: S1 (192.168.0.10?)
If I used veth or patch to connect S1 --- S2, and assign 192.168.0.10 and
192.168.0.20 respectively, would the sample rest router app work once I
configure the ryu using curl with correct ip address for S1 and S2?
I am able to ping from H1 10.0.0.2 --> S1 10.0.0.1 and 20.0.0.2 S2 -->
20.0.0.1 S1
I am also able to ping 10.0.0.2 and 20.0.0.2 from my linux server.
I am missing soemthing basic. Any suggestions on how to troubleshoot and
what to look out for will be helpful.
I can provide the ryu, ovs-vsctl and ovs-ofctl output and any tcpdump
traces for arp, icmp etc ...
Any advice or pointers appreciated.
Thanks
