Any address can have prefix length /128. Loopback can have global 
addresses as well :).

Note that although having prefix length longer than /64 seems to be 
forbidden by RFC3513 for non-000/3 unicast prefixes, using /127 and 
smaller (but bigger than /64) has gained a lot of operational popularity.
There is a mass of discussions about this in the net (search cisco-nsp, 
nanog etc list archives).

Yes, I know /127 is bad idea (see RFC3267 for details), but smaller prefix 
lengths don't have any operational impact for now in any equipment I know 
of.

So, I think Xorp shouldn't set any restrictions either. With these we 
could cause a lot of trouble for users while integrating Xorp routers 
into existing networks.
