1. Previously you said that you saw following error messages: 2014-02-12T11:04:38Z|00010|netdev_vport|ERR|gre0: IPsec requires the ovs-monitor-ipsec daemon 2014-02-12T11:04:38Z|00011|bridge|WARN|could not configure network device gre0 (Invalid argument)
If pid files are in the same OVS run directory then you should not see them any more. Is this the case? 2. ipsec_gre tunnel not showing up in ovs-dpctl output is an expected change, I believe, it was introduced in 1.10 as part of flow based tunneling. However you should still see gre_system port that is shared with ipsec_gre ports. 3. Also there was an IPsec bug in 1.10 (and in newer releases) that we fixed recently. The problem was that two iptables rules were missing. Can you verify if you have them? iptables -A INPUT -t mangle -p esp -j MARK --set-mark 1/1 iptables -A INPUT -t mangle -p udp --dport 4500 -j MARK --set-mark 1/1 4. If all of above is configured correctly, then can you verify, if you see IPsec configuration in the kernel? Do "ip xfrm policy" and "ip xfrm state" commands and search for the peer's IP address. If it does not have a trace of peer's IP address, then please make sure that you have valid configuration in OVSDB (take a look at ovs-vswitchd.conf.db man page). 5. Also, if this is the first time you are trying to set up OVS+IPsec, then I would recommend to start with PSKs and only then with PKI. Starting with PSKs will rule out any certificate issues. Later you can do the switch to PKI, if deemed so.

As you said I checked and found that the ovs-monitor-ipsec.pid file is in the same ovs run directory just like all other pid files. But the error still persists and the interface is still not getting shown at the kernel level. Please help me regarding this.

YES I did installed the IPsec daemon from the debian package for my system but I installed the ovs-vswitchd daemon from the source code for my system. Does this mean that either I have to install the openvswitch and its ipsec daemon from debian package or from their respective source codes? Also , I will make sure that the ovs-monitor-ipsec pid file is in the ovs run dir. One more thing I want to clarify is that does the openvswitch ipsec package will take care of the ipsec functionality in openvswitch automatically or do I have to make some configuration for this in the racoon daemon? Please help me regargding this.I will let you know whether this worked or not.

For this, I have installed the OpenvSwitch-IPsec package on my system and I'm running the ovs-monitor-ipsec demon. But when I'm using the following command: ovs-vsctl add-port br0 gre0 -- set interface gre0 type=ipsec_gre options:remote_ip=10.10.10.2 . The ipsec_gre interface is not getting shown at the kernel level. I checked it using the following command: ovs-dpctl show br0 When I see the OpenvSwitch logs,it is giving following error: 2014-02-12T11:04:38Z|00010|netdev_vport|ERR|gre0: IPsec requires the ovs-monitor-ipsec daemon 2014-02-12T11:04:38Z|00011|bridge|WARN|could not configure network device gre0 (Invalid argument) [Ansis]: Make sure that ovs-monitor-ipsec.pid file is in the ovs run directory (just like all other ovs pid files). I haven't been able to figure why this error is coming , as the demon is running in the background. Also I didn't found found any relevant document related to GRE over IPsec which will show how the openvswitch-ipsec demon will commiunicate with racoon in order to implement ipsec functionality on OpenvSwitch with the configuration required in order to implement this. How should I configure racoon to implement IPsec functionality? Do I need to do some more configuration regarding ipsec on openvswitch? Please help me regarding this issue.Any help would be appreciated.
