Title:
OVS agent ryu/native implementation breaks non-OF1.3 uses
Status in networking-bgpvpn:
Fix Released
Status in BaGPipe:
Fix Released
Status in neutron:
Fix Released
Bug description:
The ryu-based OVS agent variant forces the bridge Openflow version to 1.3
only [1], which breaks a few things:
- troubleshooting tools relying on ovs-ofctl, unless they specify "-O
Openflow13", will break:
version negotiation failed (we support version 0x01, peer supports version
0x04)
ovs-ofctl: br-tun: failed to connect to socket (Broken pipe)
- calling add_flow on an OVSCookieBridge derived from a bridge that is
an native.ovs_bridge.OVSAgentBridge, will fail with the same error,
because add_flow will call ovs-ofctl without specifying "-O
Openflow13" (this issue is currently hitting networking-bgpvpn: [2])
It seems like a possible fix would be to not restrict the set of
Openflow versions supported by the bridge to Openflow13, but to just
*add* Openflow13 to the set of supported versions.
