TODO: Careful vetting of information in this item.

Ports can also be separated (grouped) using single bridge with multiple VLANs. That requires assigning interfaces to correct software VLANs. //This item needs careful vetting... //

Example:

config device
	option name 'br-lan'
	option type 'bridge'
	list ports 'lan1'
	list ports 'lan2'
	list ports 'lan3'
	list ports 'lan4'

config bridge-vlan
	option device 'br-lan'
	option vlan '1'
	list ports 'lan1'
	list ports 'lan2'

config bridge-vlan
	option device 'br-lan'
	option vlan '2'
	list ports 'lan3'
	list ports 'lan4'

config interface 'home'
	option device 'br-lan.1'
	option proto 'static'
	option ipaddr '192.168.1.1'
	option netmask '255.255.255.0'

config interface 'office'
	option device 'br-lan.2'
	option proto 'static'
	option ipaddr '192.168.13.1'
	option netmask '255.255.255.0'
