Hi Gang, The only difference between this and the -00 version is that we made it clear that the suppression must take place between the FIB and the Routing Table. Previous version it was ok to do suppression between the RIB and the Routing Table.
The need for the change comes from the fact that PIM relies on the contents of the Routing Table for its operation, so it cannot be changed.

This draft is a work item of the Global Routing Operations Working Group of the IETF. Title : FIB Suppression with Virtual Aggregation Author(s) : P. Francis, et al. Filename : draft-ietf-grow-va-01.txt Pages : 27 Date : 2009-10-25 The continued growth in the Default Free Routing Table (DFRT) stresses the global routing system in a number of ways. One of the most costly stresses is FIB size: ISPs often must upgrade router hardware simply because the FIB has run out of space, and router vendors must design routers that have adequate FIB. FIB suppression is an approach to relieving stress on the FIB by NOT loading selected RIB entries into the FIB. Virtual Aggregation (VA) allows ISPs to shrink the FIBs of any and all routers, easily by an order of magnitude with negligible increase in path length and load. FIB suppression deployed autonomously by an ISP (cooperation between ISPs is not required), and can co-exist with legacy routers in the ISP.
