Hi Alex, Two quick points: * The RA route servers no longer exist. Around January 1 of this year, the NSF sponsored route servers were decomissioned. At serveral exchange points, Route Server services are now being provided by the commercially funded RSNG project (see http://www.rsng.net). Other aspects of the RA project (including some research, RPSL, and IRR management/development) have continued. * The RSNG route servers announce routes according to policy registered in the IRR. Any routes not explicitly allowed by policy (RFC-1918 routes, default, etc.) are effectively filtered in announcements to all RS peers. - Craig at Thu, 06 Mar 1997 15:39:13 GMT, you wrote:

This is a prinicpal example of why people should be filtering on both inbound & outbound announcements of default & RFC1918 address space.

Well we do this (we also filter out some other things we don't want to hear from other people), but this set me thinking. Is there anyone who actually has a good reason to propogate default and reserved addresses through the RA? Wouldn't it be a good move for the RA itself to filter these announcements (in addition to what's in the policy)?
