Explain Quantum Network Configuration, like I'm 5

From the OpenStack Networking Guide

The suggested configuration for /etc/quantum/plugins/linuxbridge/linuxbridge_config.ini to implement a single public network with multiple VLAN tenant networks is:

[vlans]
tenant_network_type = vlan
network_vlan_ranges = physnet2:100:110

[linux_bridge]
physical_interface_mappings: physnet2:eth1

However it is not clear from this how the external network is defined. If amend the bridge section:

[linux_bridge]
physical_interface_mappings: physnet2:eth1,physnet3:eth1

This raises an execption in /var/log/quantum/server.log on startup. If I amend the vlan section:

[vlans]
tenant_network_type = vlan
network_vlan_ranges = physnet2:100:110,physnet1

This works, but it's not clear if I can set that physical network as having no VLAN range (I can still create a network with a --provider:network_type vlan...

Furthermore, I cannot add multiple physical_interface_mapping entries. E.g.

[linux_bridge]
physical_interface_mappings: physnet2:eth1,physnet3:eth2

Just makes everything unhappy.
