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)?
Alex, At least in theory, it is. Read paragraph titled "The Routing Arbiter's Responsibility" in <http://www.ra.net/RADB.tools.docs/radbserv.html>.
