A Cisco 2651 with 128mb is a valid BGP speaker, these days. That's a cheap router, indeed. And, router memory is dirt cheap. > How much can we give to individual entities without endangering the > common good? The problem here is that there are MANY individual entities that are multihoming using less than RIR allocated blocks. The common good is promoted by allowing these folks to multihome, which would be effectively prohibited if all networks implimented verio-style filter policies. Your own network (Adelphia) advertises more specific /24s from larger blocks, and many blocks smaller than RIR boundaries. You almost certainly have excellent reasons for doing this, as do many service providers (i.e. the common practice of announcing the larger aggregate, then announcing smaller prefixes for each POP, at more localized transit connections). Is this a capability you are willing to lose? I hope not, as it would negatively impact your customers. The number of folks who multihome is large and growing. We should support this by promoting relatively open filtering policies and allowing /24s to be truly, globally routable. - Daniel Golding > > >At 09:01 AM 9/28/2001 -0700, Majdi S.
