Hi,
I ran into a crash when integrating a Pica8 switch with Ryu Manager running on
the following devstack image from
https://github.com/osrg/ryu/wiki/RYU-OpenStack-Folsom-environment-VM-image-file-HOWTO
The Pica8 switch was running in Open vSwitch mode, with version 1.6.1 software.
192.168.0.8 pica8 switch
192.168.0.10 openstack controller with ryu-manager
With the above devstack image running, I issued the following commands to the
Pica8 switch
ovs-vsctl --db=tcp:192.168.0.8:6633 add-br br-int -- set bridge br-int
datapath_type=pica8 other_config=datapath-id=000060EB69D29CDE
ovs-vsctl --db=tcp:192.168.0.8:6633 set-controller br-int
tcp:192.168.0.10:6633
This cause the Pica8 switch to initiate the connection, but the ryu-manager
prompted rejected and terminated the TCP connection. Below is the --verbose
output from ryu-manager.
It's worth noting that this issue doesn't happen if I removed
"ryu.app.gre_tunnel" from RYU_APPS variable in localrc file.
Could you tell me what might have been the cause of this issue?
If I don't have "ryu.app.gre_tunnel" in RYU_APPS, will I still be able to use
GRE tunnel between OVS's?
Thanks,
-------------
