Be carefull with DLSW and with "switch-port mode dynamic".
On practive labs, lots of DLSW ends, ends up on the same switches.
You can make accidentaly make a trunk over the DLSW cloud, and these port
on the switch will become a trunk port, and start spanningtree on the
native vlan, which will make some ports blocking.
In short, when doing dlsw, make sure the ports connected to the routers
involved in the LDSW are "we mode access".
