The topology tests whether the device deals correctly with VLAN 1
in a vlan.trunk:

* As a native VLAN
* As a regular (tagged) VLAN
* In a trunk where another VLAN is a native VLAN

All r* hosts should be able to ping each other and all d* hosts should
be able to ping each other.

Please note it might take a while for the lab to work due to
STP learning phase
