No.  The VIP only gets the FIB, not the RIB and definitely not the Adj-RIB.

Acknowledged.  It'd take a LOT of load-sharing to drive 72MB of 
single-path data to exceed 128MB (minus an appropriate comfort margin), 
but it could certainly be done.

So noted.  I'd think that one would have long before exceeded the DRAM 
capabilities of RSP4/8 and have moved up to RSP16, and therefore should 
have a well-practiced excuse on why they're running VIP2s (or 
underpopulated VIP4s/VIP6s) in an RSP16 chassis.
