-Using Neutron with Multiple Interfaces

-======================================

-

-The first interface, eth0 is used for the OpenStack management (API,

-message bus, etc) as well as for ssh for an administrator to access

-the machine.

-

-::

-

-        stack@compute:~$ ifconfig eth0

-        eth0      Link encap:Ethernet  HWaddr bc:16:65:20:af:fc

-                  inet addr:192.168.1.18

-

-eth1 is manually configured at boot to not have an IP address.

-Consult your operating system documentation for the appropriate

-technique. For Ubuntu, the contents of `/etc/network/interfaces`

-contains:

-

-::

-

-        auto eth1

-        iface eth1 inet manual

-                up ifconfig $IFACE 0.0.0.0 up

-                down ifconfig $IFACE 0.0.0.0 down

-

-The second physical interface, eth1 is added to a bridge (in this case

-named br-ex), which is used to forward network traffic from guest VMs.

-Network traffic from eth1 on the compute nodes is then NAT'd by the

-controller node that runs Neutron's `neutron-l3-agent` and provides L3

-connectivity.

-Neutron Networking with Open vSwitch

-====================================

-

-Configuring neutron, OpenStack Networking in DevStack is very similar to

-configuring `nova-network` - many of the same configuration variables

-(like `FIXED_RANGE` and `FLOATING_RANGE`) used by `nova-network` are

-used by neutron, which is intentional.

-

-The only difference is the disabling of `nova-network` in your

-local.conf, and the enabling of the neutron components.

-

-

-Configuration

-

-::

-

-        FIXED_RANGE=10.0.0.0/24

-        FLOATING_RANGE=192.168.27.0/24

-        PUBLIC_NETWORK_GATEWAY=192.168.27.2

-

-        disable_service n-net

-        enable_service q-svc

-        enable_service q-agt

-        enable_service q-dhcp

-        enable_service q-meta

-        enable_service q-l3

-

-        Q_USE_SECGROUP=True

-        ENABLE_TENANT_VLANS=True

-        TENANT_VLAN_RANGE=1000:1999

-        PHYSICAL_NETWORK=default

-        OVS_PHYSICAL_BRIDGE=br-ex

-

-In this configuration we are defining FLOATING_RANGE to be a

-subnet that exists in the private RFC1918 address space - however in

-in a real setup FLOATING_RANGE would be a public IP address range.
