Hi Varun, I'm very sorry for the delay. Would you mind including the Ryu-devel mailing list?
I've tested rest_vtep.py on my environment, I couldn't reproduce your issue... I used my Docker image which has Mininet and Ryu, and I create the topology which has 3 nodes and each node has 2 Mininet hosts. Docker Image: https://hub.docker.com/r/iwaseyusuke/ryu-mininet/ Version of OVS, Mininet and Ryu included in the above Docker image: root@a96d42869486:~# ovs-vsctl --version ovs-vsctl (Open vSwitch) 2.5.2 # this is apt packaged version on Ubuntu 16.04 Compiled Oct 17 2017 16:38:57 DB Schema 7.12.1 root@a96d42869486:~# mn --version 2.2.1 # this is apt packaged version on Ubuntu 16.04 root@a96d42869486:~# ryu --version ryu 4.19 Topology: +---------------+ +---------------+ | node1 | | node2 | | +-----------+ | | +-----------+ | | | s1 +----(Linux)----+ s1 | | | +-+------+--+ | (Bridge) | +-+------+--+ | | | | | | | | | | | +-+--+ +-+--+ | | | +-+--+ +-+--+ | | | h1 | | h2 | | | | | h1 | | h2 | | | +----+ +----+ | | | +----+ +----+ | +---------------+ | +---------------+ | | +---------------+ | node3 | | +-----------+ | | | s1 | | | +-+------+--+ | | | | | | +-+--+ +-+--+ | | | h1 | | h2 | | | +----+ +----+ | +---------------+ > *EventOFPErrorMsg received.* > *version=0x4, msg_type=0x1, msg_len=0x4c, xid=0xde4e44b* > * `-- msg_type: OFPT_ERROR(1)* > *OFPErrorMsg(type=0x2, code=0xf,> data=b'\x04\x0e\x01\x00\x0d\xe4\xe4\x4b\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00\x00\x00\x00\x00\x00\x02\xff\xff\xff\xff\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00\x2c\x80\x00\x05\x10\x00\x00\x00\x00\x00\x00\x00\x0a')*

Ping is still failing. Pls mention the environment properties on which this file was tested. Can't find anyone online who might have used the same script. Also, Once it start in switches it adds all the flows except arp response flow. Why is that ? according to ur thread on ryu-devel it should. This seems the main reason for arp failing.

But my ping keeps failing, After doing a lot of troubleshooting and verifying all properties are same as given in example, in verbose mode I found the following error which might give you insight. I am trying to implement the same example with three VM instead of 2. What is the ovs version it requires to work ? Mine is 2.0.2 can this be problem. Using mininet VM. ryu-version: 4.18 I would be very gratefull if you can tell me the required versions. Attached the logs if they can give insight. Sry for not using ryu-devel, souceforge is blocked on my network. (On a tight deadline, if you can help) Regards, Varun. M.E Grad
