VLAN Segmentation

Depending on the number of NICs you have in your node servers, you can use the following examples to plan your NIC assignment:

3 NIC deployment

• eth0 - untagged port for Administrative network
• eth1 (br-eth1) - port for networks: Public/Floating, Management, Storage
• eth2 (br-eth2) - port for Private network (where the number of VLANs depends on the number of tenant networks with a continuous range)

4 NIC deployment

• eth0 - port for Administrative network
• eth1 (br-eth1) - port for networks: Public/Floating, Management
• eth2 (br-eth2) - port for Private network, with defined VLAN range IDs
• eth3 (br-eth1) - port for Storage network

Routing recommendations

• Use the default routing via a router in the Public network
• Use the the management network to access to your management infrastructure (L3 connectivity if necessary)
• The administrative network or only the Fuel server (via dedicated NIC) should have Internet access
• The Storage and Private network (VLANs) should be configured without access to other networks (no L3 connectivity)
