I think we're talking about filtering the 64.0.0.0/8 prefix, EXACT prefix. That wouldn't block anyone from reaching anything as long as you only filter the /8 and not any of the more specific advertisements. My company's got a /16, a /17, and a /18 out of 64/8 and I *WANT* people to filter out the annoying 64.0.0.0/8 prefix that much of my traffic may be destined for if something explodes on my end and my routes get withdrawn.

For 64.0.0.0/8 this seems to have happened in the meantime... but now there's a route for 62.0.0.0/8 (the RIPE equivalent of 64.0.0.0/8),
sigh.
i dont know why you even allow 64/8 and/or 62/8 into your network. Filter them...
Aren't many Earthlink dialups in 64/8? Filtering that would mean his employees couldn't get Sprint DSL, and prevent millions of potential customers from reaching his web servers. That's not smart business. It's called "cutting off your nose to spite your face."
