Boo,

Okay, let's take a looky at this nice long filthy list of today
(07/24/02 6Bone Routing Report).
I cut out:
 - Prefixes from Different Origin AS
 - Unknown AS Numbers (not in 6bone registry)
 - The Top Five Most Active Prefixes (more than 1000 changes)
Those shouldn't happen either, but the below stuff is something we
shouldn't be seeing at all in the global routing tables.

By the way AS45589 (which is part of 32768 - 64511) is reserved and it
is causing a lot of crap.
Watch the cutlines for comments. 'Big' spillers are cc'd.
And avoid reading the sarcasm ;)

Ehmm announcing and accepting /128's and /64's, how many entries do we
want to have in the global routing table?
Viagenie shouldn't accept these foreigns at all, private peering okay,
but don't even try to announce it to the
rest of the world.

Cuddo's 2001:7f8:1::/64, the AMSiX IPv6 range in the US ;)

And those 2001:6e0::/32's should have been filtered too...

That last /32 is a delegation from BT-LABS:

But that doesn't mean those /32's should appear.

I wonder why UUNET gives out these more specifics to their peers, one
word "aggregate".

spread those.
