[pox-dev] executing the ip_loadbalancer

[shads s]

Hello all,

Actually from last few days I am trying to run ip_loadbalancer example
using POX and mininet.
After introducing TCP flow using iperf in mininet, it is showing
"DEBUG:iplb.00-00-00-00-00-01:No client for (IPAddr('10.0.0.2'),
IPAddr('10.0.0.6'), 56422, 5001)".
Even tcpdump shows only ARP request packets.

It will be great help if you send me the steps to run ip_loadbalancer.

*Below is the mininet topology:*
mininet> net
h1 h1-eth0:s1-eth1
h2 h2-eth0:s1-eth2
h3 h3-eth0:s1-eth3
h4 h4-eth0:s1-eth4
h5 h5-eth0:s1-eth5
h6 h6-eth0:s1-eth6
s1 lo:  s1-eth1:h1-eth0 s1-eth2:h2-eth0 s1-eth3:h3-eth0 s1-eth4:h4-eth0
s1-eth5:h5-eth0 s1-eth6:h6-eth0
c0

*Below is the POX output when TCP flow start using "iperf h2 h6" in
Mininet:*
