Gang,
I have submitted an internet-draft to the IDR group on virtual =
aggregation
(VA) =
(http://www.ietf.org/internet-drafts/draft-francis-idr-intra-va-00.txt).
This draft suggests a few changes to routers that allow operators to =
control
the size of their FIBs, shrinking them by 5x or 10x quite easily. This =
would
extend the lifetime of routers that are constrained by FIB size.
There has been a lively discussion of this on the IDR mailing list, =
including
a suggestion that FIB reduction is more important for lower tier ISPs =
(tier
2, tier 3...) than for tier 1 ISPs. Unfortunately I don't think that =
people
from smaller ISPs pay much attention to the IDR mailing list, so they =
are not
being represented in this discussion.
So I'm looking for input from folks who think that FIB reduction helps =
them,
so as to better understand their requirements.
Any help is much appreciated.
Thanks,
PF
