Hi, So what happens to multihoming assignments made by the ISP? That means the multihoming assignment can't be used as a backup. If the customer's connection to the ISP which made the multihoming assignment gets lost, then it can't use its multihoming assignments (say a /24) to get traffic from some other ISP?! Thanks to all, Harsha. On Wed, 13 Nov 2002, Buddy Bagga wrote:
Greets,
Look at <http://www.nanog.org/filter.html>. If I remember correctly, Verio used to filter prefixes longer than /19s in classful A range. Apparently this isn't the case anymore. But it would be naive to think that ISP only filter prefixes longer than /24.
Cheers,

Are there some ISPs who filter prefixes longer than /19 or a /20?. I thought they filtered only prefixes which are longer than /24?
