- <vans163> anyone worked with connecting OVS/OVN to physical networks?
- <vans163> for example to have dedicated servers be on private lans with virtual ones
- <vans163> I think a programmable router is needed for this?
- <vans163> Like is this needed barefoot chip?
- <russellb> you can do physical network integration in 4 ways
- <russellb> 1) OVN supports top-of-rack based L2 gateways based on the hardware_vtep ovsdb schema
- <russellb> 2) OVN supports L2 gateways via a linux host running ovn-controller
- <russellb> 3) OVN supports connecting VMs directly to a physical network - you do this by adding a special "localnet" port to a logical switch, which tells OVN that the logical switch is actually direct connectivity to a physical network
- <russellb> 4) OVN supports L3 gateway routers that can route between a virtual, overlay network, and a physical network
- <russellb> vans163: github gist
- <russellb> that's a quick overview of #3
- <vans163> that #3 I assume will connect you to a physical vlan, but you still need something programable that you can have define that VLAN in the physical router/switch (if tagging)
- <russellb> yes, you need to also provision your underlay for that vlan
- <russellb> via whatever means suits you
- <russellb> ovn can't do it
- <russellb> you use ansible by chance?
- <russellb> it has some switch config modules you can use for this sort of thing ...
- <russellb> ansible network automation
- <russellb> but there are no shortage of ways to do this stuff
