Hello,
I am doing the ODL beryllium controller "Network re-provisioning Time"
test with *miniedit*(*2.2.0.1* version).
The ODL controller(distribution-karaf-0.4.0-Beryllium) is running in
reactive mode. OVS version is *2.3.2*.
I created the topology with 4 switch's and 2 host's(Refer:
miniedit.jpg). The connection details are following in mininet,
mininet> net
h1 h1-eth0:s1-eth3
h2 h2-eth0:s4-eth3
s1 lo: s1-eth1:s2-eth1 s1-eth2:s3-eth2 s1-eth3:h1-eth0
s2 lo: s2-eth1:s1-eth1 s2-eth2:s4-eth2
s4 lo: s4-eth1:s3-eth1 s4-eth2:s2-eth2 s4-eth3:h2-eth0
s3 lo: s3-eth1:s4-eth1 s3-eth2:s1-eth2
c0
mininet> xterm h1
I started the ping(Ex: ping 10.0.0.2) from interface h1-eth0(10.0.0.1)
to h2-eth0(10.0.0.2) .
ODL controller sends the Flow_Mod to OVS and ping data flows via h1-eth0
--> s1-eth3 --> S1-eth2 --> s3-eth2 ---> S3-eth1--> S4-eth1 --> s4-eth3
--> h2-eth0.
The ping 10.0.0.2 is not succeed when I down the active path link
between s3-eth1 - S4-eth1.
ODL controller does not re-provisioning data to redundant active path
via h1-eth0 --> s1-eth3 --> S1-eth1 --> s2-eth1 ---> S2-eth2--> S4-eth2
--> s4-eth3 --> h2-eth0.
The switch S1, S2 & S3 send the packet-in(ARP) message to controller but
the ODL controller send the packet-out(ARP) message with old in-port and
out-port to switch s1 & S3 only.
Could you please clarify Whether I am missing any configuration to
re-provisioning the data traffic ?
Note: Only one time I saw the ODL controller re-provisioning the path
out of 6 times.
Let me know if you need any more information.
Thanks and Regards,
Selvakumar Murugasekaran.
