Hi,
I am trying to setup a local SDN network using physical hosts. My setup is
as follows:
OpenDayLight Controller (Host4)
(11.0.0.1)
|
|
(eth0: 11.0.0.2)
Host1
-------------------------------OpenvSwitch----------------------------------Host2
(11.0.0.5) (eth1: 11.0.0.3) Host3 (eth2:
11.0.0.4) (11.0.0.6)
Each of the machines have Ubuntu 14.04 Kernel version: 3.13.0. The
openvswitch version is 2.3.0.
The hosts and controller are connected to the switch via physical NIC cards.
The output of ovs-vsctl show is as follows:
Bridge "br0"
Controller "tcp:11.0.0.1:6633"
is_connected: true
Port "eth2"
Interface "eth2"
Port "br0"
Interface "br0"
type: internal
Port "eth1"
Interface "eth1"
The output of ovs-ofctl show br0:

OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0
After the setup is up, when I try to ping from Host2 to Host1, the ping
does not go through. I get the message "Destination Host Unreachable" and
only one flow rule is installed in the OpenvSwitch.
NXST_FLOW reply (xid=0x4):
cookie=0x0, duration=5.022s, table=0, n_packets=0, n_bytes=0, idle_age=5,
priority=1,ip,nw_dst=11.0.0.6 actions=mod_dl_dst:00:1d:09:8b:60:fa,output:2
But once Host1 starts sending some traffic, the following pings from Host2
succeeds. Same is the case other way round too.
I am unable to point where the configuration is failing.
If anybody can guide me, it would be of great help!
Thanks,
Shruti
