Hi,
I'm currently setting up GRE tunnelling. ( Scientific Linux 6.3, Folsom,
openvswitch 1.7.1 )
The flow trough the br-tun is not allowed because the quantum-ovs-agent sets
the flow of the br-tun to drop:
ovs-ofctl dump-flows br-tun
NXST_FLOW reply (xid=0x4):
cookie=0x0, duration=1264.414s, table=0, n_packets=2271, n_bytes=96966,
idle_age=1, priority=1 actions=drop
The GRE tunnel starts to work if I manually set following:
"ovs-ofctl add-flow br-tun action=normal"
Result: "tcpdump -ni eth1 proto gre"
11:54:03.591397 IP 172.16.8.163 > 172.16.8.162: GREv0, key=0x0, length 54: ARP,

A patch interface is created on both the bt-int and br-tun:
Bridge br-int
Port patch-tun
Interface patch-tun
type: patch
options: {peer=patch-int}
Bridge br-tun
Port patch-int
Interface patch-int
type: patch
options: {peer=patch-tun}
There also seems to be traffic going across the patch devices according to
"ovs-dpctl show -s"
Is there something else I am missing?
My ovs-agent config:
[OVS]
tenant_network_type = gre
enable_tunneling = True
tunnel_id_ranges = 1:1000
local_ip = 10.10.10.10
integration_bridge = br-int
tunnel_bridge = br-tun
Thanks,
Robert van Leeuwen
