@item dump graph | digraph
Dump a graph of the VPN in dotty format.
Nodes are colored according to their reachability:
red nodes are unreachable, orange nodes are indirectly reachable, green nodes are directly reachable.
Black nodes are either directly or indirectly reachable, but direct reachability has not been tried yet.
@item info @var{node} | @var{subnet} | @var{address}
Show information about a particular @var{node}, @var{subnet} or @var{address}.
