Re: [ovs-discuss] [ovs-dev] connect VM on OVN/OVS and BMS on L2

[Tony Liu via discuss]

Hi Numan,

Provider VLAN networks is able to connect VM and BMS on L2.
I am going to push this topic further.

Provider VLAN network is different from regular virtual network.
It seems that I can't create a logical router to connect a provider VLAN
and regular VN. The way I am using provider VLAN is as external network
whose GW is on physical router. Also in a multi-tenancy cloud, provider
VLAN network can't be created by user. I wonder if we can build a regular
VN to connect VM and BMS?

OVN is using Geneve which is not commonly supported by networking devices.
VxLAN doesn't seem to be an option cause OVN needs Geneve to carry metadata.
I see some vxlan supports in OVN but not sure how it works or for which case 
exactly.

Tungsten Fabric supports this because it uses vxlan as the overlay. To connect 
VM
to BMS, vrouter will create a vxlan from compute node to BMS VTEP (typically 
the ToR).
That's how BMS is brought into overlay by vxlan, and will be treated just like 
a VM.
With the EVPN support in control plane, routing info is populated between 
vrouter
and VTEPand. And with some orchestration to networking devices, the networking
support to BMS is seamless. One concern is that no SG for BMS, which can be
actually supported by networking device.

Can the similar supported by OVN or any other overlay solution supported by OVN
to connect BMS?


Thanks!
Tony

It is definitely supported with open stack.

I think you need to create a provider vlan neutron network.

For this you need to create a localnet port in the logical switch.

Something like this:

ovn-nbctl ls-add public
# localnet port
ovn-nbctl lsp-add public ln-public
ovn-nbctl lsp-set-type ln-public localnet
ovn-nbctl lsp-set-addresses ln-public unknown
ovn-nbctl lsp-set-options ln-public network_name=public

# create a few VM ports

ovn-nbctl lsp-add public pub-port1
ovn-nbctl lsp-set-addresses pub-port1 "50:54:00:00:00:03
172.168.0.100"  (assuming your L2 network is 
172.168.0.0/24)

ovn-nbctl lsp-add public pub-port2
ovn-nbctl lsp-set-addresses pub-port2 "50:54:00:00:00:04 172.168.0.101"

# On the compute node(s) where you create the VMs

ovs-vsctl set open . external_ids:ovn-bridge-mappings="public:br-ex"

ovs-vsctl add-br br-ex
ovs-vsctl add-port eth1  # assuming eth1 is your physical interface
connecting to your L2 switch

After this connectivity from your VM (bound to logical port pub-port1)
should be able to communicate to your BMS.
