Example 2: HA + Neutron with GRE

As a model example, the following configuration is used:

• Deploying mode: Multi-node HA
• Networking model: Neutron with GRE

Hardware and environment:

• 7 4 servers with two 1Gb/s ethernet NIC and IPMI
• 1 Cisco Catalyst 3750 switch (2950 Switch)
• Independent out of band management network for IPMI
• Connection to the Internet or/and DC network via a router called Gateway and IP 172.16.1.1

Node servers roles

• 1 server as Fuel Node (2G Dual Core)
• 3 1 servers as Controller Node (8G Quad Core)
• 1 server as Cinder Node (8G Quad Core)
• 2 1 servers as Compute Node - (Dell 620 32G 8 core)

Network Configuration Plan:

• Floating/Public network 172.16.0.0/24 in VLAN 100 (untagged on servers)
• Floating IP range 172.16.0.130 - 254
• Internal network (private) 192.168.111.0/24
• Gateway 192.168.111.1
• DNS 8.8.4.4, 8.8.8.8
• Tunnel ID range 2 - 65535
• Management network 192.168.0.0/24 in VLAN 101
• Storage network 192.168.1.0/24 in VLAN 102
• Administrative network (for Fuel) 10.20.0.0/24 in VLAN 103

Network Parameters

• Fuel server: IP 10.20.0.2/24
• Default gateway: 10.20.0.1
• DNS: 10.20.0.1

Note

The Internet and rest of DC access via Public network (for OpenStack Nodes) and Administrative network (Fuel server).

From server side, ports with following VLAN IDs are used:

• eth0 - Administrative VLAN 103 (untagged)
• eth1 - Public/Floating VLAN 100 (untagged), Management VLAN 101 (tagged), Storage VLAN 102 (tagged)

Detailed port configuration

The following table describes port configuration for this deployment.

G0/3	Compute Node 1	eth0	untagged	103
G0/4	Compute Node 1	eth1	tagged	100(untagged), 101, 102
G0/5	Compute Node n	eth0	tagged	103
G0/6	Compute Node n	eth1	tagged	100(untagged), 101, 102
G0/7	Controller Node 1	eth0	tagged	103

G0/9	Controller Node 2	eth0	tagged	103
G0/10	Controller Node 2	eth1	tagged	100(untagged), 101, 102
G0/11	Controller Node 3	eth0	tagged	103
G0/12	Controller Node 3	eth1	tagged	100(untagged), 101, 102
G0/13	Cinder Node	eth0	tagged	103
G0/14	Cinder Node	eth1	tagged	100(untagged), 101, 102
G0/24	Router (default gateway)		untagged	100
