Oracle Openstack 4.0.1 - Multiple External Networks with Flat Provider Network on VLAN over Bonding Interfaces Do Not Work (Doc ID 2398027.1)

Last updated on MAY 18, 2021

Applies to:

Oracle OpenStack for Oracle Linux - Version OpenStack 4.0.1 and later
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64


Network setup on network nodes:
On each network node, there is one bonding device bond0 designed for neutron external network, two vLAN networks created on this bonding device namely bond0.100 and bond0.101.

Kollacli property setup on master node:
$ kollacli property set neutron_external_interface bond0.100,bond0.101
$ kollacli property set neutron_bridge_name br-ex1,br-ex2

Create two external networks with associated routers on flat provider-network-type:
$ docker-ostk openstack network create --external --provider-network-type flat --provider-physical-network physnet1 ExternalNetwork1
$ docker-ostk openstack subnet create --no-dhcp --allocation-pool start=192.XXX,end=192.XXX --subnet-range 192XXX --gateway 192.XXX --dns-nameserver 10.XXX --network ExternalNetwork1 ExternalSubnet1
$ docker-ostk openstack network create --external --provider-network-type flat --provider-physical-network physnet2 ExternalNetwork2
$ docker-ostk openstack subnet create --no-dhcp --allocation-pool start=192XXX,end=192.XXX --subnet-range 192.XXX --gateway 192.XXX --dns-nameserver 20.XXXX --network ExternalNetwork2 ExternalSubnet2
$ docker-ostk openstack router create router1
$ docker-ostk openstack router create router2
$ docker-ostk openstack router set --external-gateway ExternalNetwork1 router1
$ docker-ostk openstack router set --external-gateway ExternalNetwork2 router2

Create two instances (instance1 with floating IP Address on ExternalNetwork1 via router1 and instance2 with floating IP Address on ExternalNetwork2 via router2), either one instances or both could not connect with external networks.
