RE: cogent bgp filtering policies?

["John van Oppen" <john () vanoppen com>]

That software might be a good solution for sending them updates, heck a
script sending it out every time it detects an update might also cause
them to get more excited about automating updates.   ;)   We also had
issues with them wanting a paper (or faxed) LOA which seemed a bit
onerous given the number of prefixes we announce.

The le 24 matches should have been easy since the reason we wanted them
were because we have customers using their own ASNs to announce
sub-allocations of our space, a quick look on their part the first time
we made the request would have shown that the sub allocations were all
originated from downstream ASNs from our network.   

If anyone has an engineering contact at cogent (ie not the support
contact) I would love to talk to them as it seems support department
front-end is the problem and not necessarily cogent's actual policies.

Cogent does not support IRR.  Since you're using IRR yourself, Richard
Steenbergen's IRRPT (irrpt.sf.net) has a script called 'irrpt_nag'
which is good for sending automated requests for prefix-list updates
with providers that continue to process them manually.

You can (and should) ask that Cogent's "Engineering" department okay
you for support for de-aggregation down to the /24 level or more
specific.  They will with proper justification or a general feeling
that you've got good reason and aren't just looking to gratuitously
de-aggregate prefixes for no reason.

Drive Slow,
