Hmmmmmm......  I think I see what you're getting at.  Do I understand 
correctly that you are using 10.1.0.1-62 for loopbacks with the 32
bit mask?  And that you are using the 10.1.0.65-254 range - using 
the 30 bit mask - for the point to point links?

If this is the case, I'm unsure as to what problem you would be
having with Netview - so long as you are discovering your routers
by loopback address. 

Perhaps you could clarify as your original message leads me to
believe that Netview is for some reason applying a 30 bit mask
against an address that in fact has the 32 bit mask.  Which sounds
like a discovery problem or some such...
