# This is an example of a multi-NIC bonded configuration for NetworkManager
# to create the required bridges for OpenStack-Ansible. In your environment,
# the configuration may differ.
# The example shows a compute host setup where compute hosts also serve
# as network gateway nodes.
# Assuming eth0/1 and eth2/3 are dual-port NICs, eth0 is paired with eth2
# and eth1 with eth3 to improve resiliency in case one NIC card fails.

# Here is the configuration for the control plane bond, which handles
# the control plane traffic:

[connection]
id=Bond connection 1
type=bond
interface-name=bond0

[bond]
downdelay=0
miimon=1
mode=802.3ad
updelay=0

# # Slave interface configuration (includes eth0 and eth2):

# bond0 port 1 (eth0)
[connection]
id=bond0 port 1
type=ethernet
controller=bond0
interface-name=eth0
port-type=bond

# bond0 port 2 (eth2)
[connection]
id=bond0 port 2
type=ethernet
controller=bond0
interface-name=eth2
port-type=bond

# Bridge interface for host and container management:

[connection]
id=br-mgmt
type=bridge
interface-name=br-mgmt

[ipv4]
address1=172.29.236.4/22
method=manual

# Bridge interface for storage network (optional):

[connection]
id=br-storage
type=bridge
interface-name=br-storage

# VLAN interface for container/host management carried over bond0:

[connection]
id=VLAN connection 1
type=vlan
controller=br-mgmt
port-type=bridge

[vlan]
id=10
parent=bond0

# Storage network VLAN interface (optional)

[connection]
id=VLAN connection 2
type=vlan
controller=br-storage
port-type=bridge
[vlan]
id=20
parent=bond0

### This bond carries VLAN and VXLAN traffic, ensuring isolation from
# the control plane traffic on bond0.

# And config for data plane bond:

[connection]
id=Bond connection 2
type=bond
interface-name=bond1

[bond]
downdelay=0
miimon=1
mode=802.3ad
updelay=0

# And it's slaves:

# bond1 port 1 (eth1)

[connection]
id=bond1 port 1
uuid=f6d6ae3b-db16-4bc0-b996-fad0d894186d
type=ethernet
controller=bond1
interface-name=eth1
port-type=bond

# bond1 port 2 (eth3)

[connection]
id=bond1 port 2
type=ethernet
controller=bond1
interface-name=eth3
port-type=bond

# OpenStack Networking VXLAN (tunnel/overlay) bridge interface:

[connection]
id=br-vxlan
type=bridge
interface-name=br-vxlan

# Bridge interface for storage network (optional):

[connection]
id=br-storage
type=bridge
interface-name=br-storage

# VXLAN (tunnel/overlay) VLAN interface for OpenStack networking:

[connection]
id=VLAN connection 3
type=vlan
controller=br-vxlan
port-type=bridge
timestamp=1752076721

[ethernet]

[vlan]
flags=1
id=30
parent=bond1

# The br-vlan bridge originates from older setups using containerized Neutron agents.
# It is no longer needed or recommended — you can use the physical interface directly,
# which allows full utilization of the entire physical NIC without an extra bridge.

id=Bond connection 2
