Reference map vs OSPF map:

Both same: super
Router missing in reference map: was not added, pls add
Router missing in OSPF map: probably down?
	- The rest should be connected, otherwise this is weird (our bug?)
Network missing from ref: this is strange, maybe reconfiguration?
	- If behind a previously unknown router, it's less strange
Network missing from OSPF: All links down? Seems wrong.
Connection missing from ref: should not happen unless reconfiguring
	- We can draw that without config as straight line. This feels much safer than autopositioning networks or routers.
Conn missing from OSPF: link down, quite likely.



Analysis functions:
- SPOFs
- Routing trees
	- Note: Link costs are asym? Cost is from router to network, and network assumes all routers are there?
