After establishing initial host management network connectivity using the bond0 interface, modify the /etc/network/interfaces file as described in the following procedure.
Procedure 4.1. Modifying the network interfaces file
Physical interfaces:
# Physical interface 1
auto eth0
iface eth0 inet manual
bond-master bond0
bond-primary eth0
# Physical interface 2
auto eth1
iface eth1 inet manual
bond-master bond1
bond-primary eth1
# Physical interface 3
auto eth2
iface eth2 inet manual
bond-master bond0
# Physical interface 4
auto eth3
iface eth3 inet manual
bond-master bond1
Bonding interfaces:
# Bond interface 0 (physical interfaces 1 and 3)
auto bond0
iface bond0 inet static
bond-slaves eth0 eth2
bond-mode active-backup
bond-miimon 100
bond-downdelay 200
bond-updelay 200
address HOST_IP_ADDRESS
netmask HOST_NETMASK
gateway HOST_GATEWAY
dns-nameservers HOST_DNS_SERVERS
# Bond interface 1 (physical interfaces 2 and 4)
auto bond1
iface bond1 inet manual
bond-slaves eth1 eth3
bond-mode active-backup
bond-miimon 100
bond-downdelay 250
bond-updelay 250
If not already complete, replace HOST_IP_ADDRESS, HOST_NETMASK, HOST_GATEWAY, and HOST_DNS_SERVERS with the appropriate configuration for the host management network.
Logical (VLAN) interfaces:
# Container management VLAN interface
iface bond0.CONTAINER_MGMT_VLAN_ID inet manual
vlan-raw-device bond0
# OpenStack Networking VXLAN (tunnel/overlay) VLAN interface
iface bond1.TUNNEL_VLAN_ID inet manual
vlan-raw-device bond1
# Storage network VLAN interface (optional)
iface bond0.STORAGE_VLAN_ID inet manual
vlan-raw-device bond0
Replace *_VLAN_ID with the appropriate configuration for the environment.
Bridge devices:
# Container management bridge
auto br-mgmt
iface br-mgmt inet static
bridge_stp off
bridge_waitport 0
bridge_fd 0
# Bridge port references tagged interface
bridge_ports bond0.CONTAINER_MGMT_VLAN_ID
address CONTAINER_MGMT_BRIDGE_IP_ADDRESS
netmask CONTAINER_MGMT_BRIDGE_NETMASK
dns-nameservers CONTAINER_MGMT_BRIDGE_DNS_SERVERS
# OpenStack Networking VXLAN (tunnel/overlay) bridge
auto br-vxlan
iface br-vxlan inet static
bridge_stp off
bridge_waitport 0
bridge_fd 0
# Bridge port references tagged interface
bridge_ports bond1.TUNNEL_VLAN_ID
address TUNNEL_BRIDGE_IP_ADDRESS
netmask TUNNEL_BRIDGE_NETMASK
# OpenStack Networking VLAN bridge
auto br-vlan
iface br-vlan inet manual
bridge_stp off
bridge_waitport 0
bridge_fd 0
# Bridge port references untagged interface
bridge_ports bond1
# Storage bridge (optional)
auto br-storage
iface br-storage inet static
bridge_stp off
bridge_waitport 0
bridge_fd 0
# Bridge port reference tagged interface
bridge_ports bond0.STORAGE_VLAN_ID
address STORAGE_BRIDGE_IP_ADDRESS
netmask STORAGE_BRIDGE_NETMASK
Replace *_VLAN_ID, *_BRIDGE_IP_ADDRESS, and *_BRIDGE_NETMASK, *_BRIDGE_DNS_SERVERS with the appropriate configuration for the environment.
