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. Deepak Jain AiNET On Tue, 13 Feb 2001, Stephen J.
