Hi Zhi Chang,
I believe the answer is that the physical network (aka fabric) should provide
routing between those two subnets. This routing between segments is implicit in
the idea of a multi-segment network, and is entirely independent of routing
between virtual _networks_ (which is done by a Neutron router object connecting
those networks).
Hope that helps!
Neil

any segments when creating port

Hi, shihanzhang.
I still have a question about routed network. I have two subnets. One is
10.1.0.0/24 and the other is 10.1.1.0/24. I create two instances in each host.
Such as 10.1.0.10 and 10.1.1.10.
My question is, how does 10.1.0.10 connect to 10.1.1.10 ? There is no any
gateway( 10.1.0.1 and 10.1.1.1 ) in each subnet.
Hope four your reply. ;-)
Thanks

Hi, shihanzhang.
Thanks for your advice. Now I can created ports successfully by your advice.
Thanks

Hi Zhi Chang,
Maybe you should add a config option in [ovs] section: bridge_mappings =
public:br-ex, physnet1:br-physnet1 to handle the provider network 'physnet1'.
Thanks,

hi Zhi chang,
Could you provide your ml2_conf.ini for ovs agent, I guess the reason is that
your ovs-agent on host devstack can't handle the related segment id.
Thanks,

Hi, all.
Recently, I watch the OpenStack Summit video named ' Scaling Up OpenStack
Networking with Routed Networks '. Carl and Miguel made this topic. I learned
a lot of your topic. Thanks.
But I have some questions about the demo in the topic.
I do some steps according to the topic.
First, creating two networks like this:
neutron net-create multinet --shared --segments type=dict list=true
provider:physical_network=physnet1,provider:segmentation_id=2016,provider:network_type=vlan
provider:physical_network=physnet2,provider:segmentation_id=2016,provider:network_type=vlan
Second, I get two segments after creating this network. I get these segments by
using " openstack network segment list ".
Third, I create two subnets by these segments by using this command "
neutron subnet-create --ip_version 4 --name multi-segment1-subnet [net-id]
10.1.0.0/24 --segment_id [segment-id]
neutron subnet-create --ip_version 4 --name multi-segment2-subnet [net-id]
10.1.1.0/24 --segment_id [segment-id]
"
At last, I want to create a port with host_id. My local environment contains
two compute nodes, one is named "devstack" and the other is "devstack2". So I
use this command " neutron port-create --binding:host_id=devstack [net-id] ".
Exception happens in neutron server. The exception says "
Host devstack is not connected to any segments on routed provider network
[net-id]. It should be connected to one." I can not get this exact point about
this exception.
Why does the "routed network" have relationship with host?
How they work together between "host info (compute node ?)" and "routed
network"?
What should I do if I want to get rid of this exception?
Hope for your reply. Especially Carl and Miguel. ;-)
Many Thanks
Zhi Chang
