Hello,
In such case like You described, ports will be bound with openvswitch
mechanism driver because this agent will be found as alive on host. So
linuxbridge mechanism driver will do nothing for binding such ports.

Hi, Kevin. If I load openvswitch and linuxbridge mechanism drivers in
neutron server, and running ovs-agent in compute nodes. What does
openvsitch mechanism driver do? What does linuxbridge mechanism do? I
think there must have some differences between the openvswitch and the
linuxbridge mechanism driver. But I can't get the exact point about the
two mechanism drivers when running ovs-agent in compute nodes now.

Note that with the openvswitch and linuxbridge mechanism drivers, it
will be safe to have both loaded on the Neutron server at the same time
since each driver will only bind a port if it has an agent of that type
running on the host.

Hello,
I don't know what is hierarchical port binding but about mechanism
drivers, You should use this mechanism driver which L2 agent You are
using on compute/network nodes. If You have OVS L2 agent then You
should
have enabled openvswitch mechanism driver.
In general both of those drivers are doing similar work on
neutron-server side because they are checking if proper agent type is
working on host and if other conditions required to bind port are
valid.
Mechanism drivers can have also some additional informations about
backend driver, e.g. there is info about supported QoS rule types for
each backend driver (OVS, Linuxbridge and SR-IOV).
BTW. IMHO You should send such questions to

Hi, all
First of all. Happy New year for everyone!
I have a question about mechanism drivers when using ML2 driver.
When should I use openvswitch mechanism driver ?
When should I use linuxbridge mechanism driver ?
And, when should I use openvswitch and linuxbridge mechanism drivers ?
In my opinion, ML2 driver has supported hierarchical port binding. By
using
hierarchical port binding,
neutron will know every binding info in network topology, isn't it? If
yes,
where I can found the every binding info. And what the relationship
between
hierarchical port binding and mechanism drivers?
Hope for your reply.
Thanks
Zhi Chang
