OSPF Visualizer?

[lorell at hathcock.org (Lorell Hathcock)]

All:

 

I am a small Wireless ISP in need of an OSPF visualizer that does not cost
an arm and a leg.

 

I would like one that can listen to LSA's in each area and build a map of
the network.

 

I anticipate that I could trouble OSPF issues with such a system.

 

Any open source projects?

 

Thanks in advance,
