I haven't sent off for lab17 yet but the ospf demand circuit should and only
needs to be put on one end.
The circuit will come up and a neigbor relationship will be formed and then
the ciruit will go down until an LSA change (a better route dies). I
haven't tried demand circuit over virtual link yet either.
