Route count

Hi,

Does anyone know a more efficient way to get a count of the number of 
routes than to do something like the following?

    # ip route show table $TABLE | wc -l

I'm doing something where I'd like to instrument the number of 
(unreachable / null) routes once a minute and I'd like to avoid 
unnecessary load on the system.

It seems to me like there should be a counter somewhere that I can just 
read instead of needing to enumerate every single route in the table.
