Just guessing here, but I'd not be surprised if the explanation involved one
or more of the phrases "BGP Flap", "temporary outage", "backhoe/shark/chucklehead".

4AM local might very well be inside a maint window too...

Hi Folks,

Sorry about that, something seems to have broken when the script was run
earlier on today. The table in the view I use was 140k prefixes then,
and is now back up to the normal 159k again.

It wold be nice to see how things gradually change as the 5% becomes larger.

Its probably not getting the routes - I see 915 AS's in the routing table using 32 bit AS numbers (http://www.potaroo.net/tools/asn32/)

In RIS we saw 918 32 bit ASNs advertising about 2200 prefixes on 2011-03-19.

The report is as good as what is in the RIR allocation databases, as I
grab those from the RIR public listings about 2 hours before the report
is run. So if it was allocated, it wasn't listed in the file that I pick
up. I'll investigate why.

It is as accurate as the data I have access to. ;-) But I'd be delighted
to hear suggestions for improvements.

You could try using http://bgp.potaroo.net/stats/nro/status.joint.txt

I use this as the basis of the bogon listing on the CIDR Report and I don't seem to be pickling up these false positives.

I think you mean 512k IPv4 with 256k of IPv6 (taking double space).

Make sure you check your tcam profiles :)

By that point router vendors will hopefully have moved to 64-bit CPUs.
18446744073709551616 routes will hopefully not happen until after I retire,
so you young whippersnappers will be on your own on that one. ;)

if you're still on a platform with 40Mbit cams it's beginning look kinda
tight as an internet router. you've probably got less than a year to
figure out what to do about this.

an f10 ej linecard cam paritioning scheme for example looks something like.

CamSize : 40-Meg

We we long ago have switch to routers that are capable of handling
more or we will succeed in making multi homing work well enough
with PA addresses that we don't get there.

512K of IPv4? That's getting close!

I know a few people had issues around the 256k barrier from tcam based platforms. Expect a lot of BGP instability as people react to 512k entries in their fib
Re: Weekly Routing Table Report [ In reply to ]
Hello Brough,

Very well spotted!! :-)

I finally fixed a problem in my analysis programme which was miscounting
the extended range of 32-bit ASNs (those from 65536 and above). It
wasn't counting them at all in fact, something spotted by one of our
industry colleagues a couple of months back. So the jump is caused by that.

Misery for me now is I have to go back through a few years of daily
reports and figure out when I made the change to cause the breakage. And
rerun everything (sigh).

The other bonus of the fix is that I'm dealing with 32-bit ASNs properly
now - I'm catching the 65536 to 131071 range as bogons, and also
catching any origin ASNs from above 458752 as bogons too.

Thanks!
