Configuring a bond + vlan + bridge is not completely straightforward or clear
with nmcli. An example should be added such as:

nmcli conn add type bond con-name bond0 ifname bond0 mode 802.3ad ipv4.method
disabled ipv6.method ignore


nmcli connection add type ethernet con-name bond0-eth1 ifname eth1 master bond0
slave-type bond
nmcli connection add type ethernet con-name bond0-eth2 ifname eth2 master bond0
slave-type bond

nmcli connection add type bridge con-name net_18 ifname net_18 ipv4.method
disabled ipv6.method ignore

nmcli connection add type vlan con-name bond0.18 ifname bond0.18 dev bond0 id
18 master net_18 slave-type bridge




This is suitable for libvirt/vms to use the bridges.
