so why bother advertising all these unnecessary blocks increasing the bgp table size and increasing traffic when you can just add a default route to null0 as per previous email?? On Tue, 13 Feb 2001, Deepak Jain wrote:
You can configure the BGP feed to set next hop to an unused interface or null0 or (your hardware's efficient null spot). The idea of BGP feed, if I am not mistaken, is to allow dynamic configuration/reconfiguration as blocks are allocated to keep from having to revise hundreds of routers' filters.
In practice, I am not sure I'd feel comfortable with it, but surely many would use it.

Only I drop my unallocated/private packets at my core routers, if you set up routes to ARIN/whoever then I would transmit out those packets and my transits would carry them for me if I dont connect directly..
extra traffic all round really. why not just let the core routers bin the rogue packets? (ip route 0.0.0.0 0.0.0.0 null0)

It would seem to me that ARIN and its counterparts should get together and provide a "blackhole" BGP feed (the NBL?) where all packets destined for unallocated, restricted, or private space go bye-bye.
