Yes, such a document could be useful. We're using a prefix-list as shown below. We could use it as a starting-point to establish a standard prefix filter, or as Randy put it, a prefix filter technical coding advice.
What is also very helpful is to point out the usefulness of anti-spoofing rules - ie filter your own netblocks when they are announced to you, _including_ more specific routes ;-)
Hm. Yes. But this gets us into a controversial issue since filtering more specifics from your own netblocks means your multihomed customers don't get connectivity to you when the line between you and them is down. I am a bit worried about expanding the scope of this to the point where we get bogged down in arguments about such practices. It seems to me that there is a large body of non-controversial practices that simply require collation and documentation in order to acheive a major effect. We should stick to those, at least in the first instance. Phil
