We have two logical ports, one on each hypervisor, # that OVN will connect to physnet1. # # The way to accomplish this in OVN is to create a logical switch for each # logical port. In addition to the normal logical port, each logical switch # has a special "localnet" port, which represents the connection to physnet1. # # In this setup we see the view of this environment from one of the hypervisors. set -o xtrace ovs-vsctl add-br br-eth1 ovs-vsctl set open . external-ids:ovn-bridge-mappings=physnet1:br-eth1 ovn-sbctl chassis-add fakechassis geneve 127.0.0.1 for n in 1 2 3 4; do ovn-nbctl ls-add provnet1-$n ovn-nbctl lsp-add provnet1-$n provnet1-$n-port1 ovn-nbctl lsp-set-addresses provnet1-$n-port1 00:00:00:00:00:0$n ovn-nbctl lsp-set-port-security provnet1-$n-port1 00:00:00:00:00:0$n ovn-nbctl lsp-add provnet1-$n provnet1-$n-physnet1 ovn-nbctl lsp-set-addresses provnet1-$n-physnet1 unknown ovn-nbctl lsp-set-type provnet1-$n-physnet1 localnet ovn-nbctl lsp-set-options provnet1-$n-physnet1 network_name=physnet1 done ovs-vsctl add-port br-int lport1 -- set Interface lport1 external_ids:iface-id=provnet1-1-port1 ovs-vsctl add-port br-int lport2 -- set Interface lport2 external_ids:iface-id=provnet1-2-port1 ovn-sbctl lsp-bind provnet1-3-port1 fakechassis ovn-sbctl lsp-bind provnet1-4-port1 fakechassis
