Interesting, we use the 'table-map' feature quite 
extensively for policy accounting, but didn't know one of 
its applications is as you describe.

I'm just not sure how an ASR1001 would react when the FIB 
has overflowed. I don't really care as our route reflectors 
don't normally forward traffic, but it maybe strange things 
could happen. Don't know, never tested.

Cheers,

Mark.
