As far as I know, this is currently not possible. I'd like to implement
something like a "virtual device" in the future, representing the cloud
that links several networks together. Then you'd have one big network
map with all locations in it and the MPLS backbone as a single dummy
device in the center.

In the mean time, perhaps this dirty workaround might work:
* Take some old switch that speaks SNMP; just give it an uplink and
management address so Netdisco can discover it. Disable any discovery
protocols (CDP/LLDP) on the uplink.
* Give it a nice name like "Dummy MPLS for Netdisco".
* Discover it in Netdisco.
* Create entries in the topology file (see manpages) to map interfaces
on this switch to the interfaces on other switches, which are in fact
connected to the MPLS backbone.

Now your smaller networks are all connected to a single switch as far as
Netdisco is concerned, making it one big network to show in the topology
map.
