00:aa:bb:01:23:45
by Baldur Norddahl 24 Aug '20

Hello By accident I noticed several of my VPLS instances have 00:aa:bb:01:23:45 in the MAC table. We never sent anything just received a little traffic from that. Obviously not a real MAC address so I tried to search Google for it. I find several hits with apparently ADSL users doing pppd (which we do not have). Anyone have any idea what this could be? Regards, Baldur

Two precursors to the system we have today. Both proposed some form of including PKI-related matter in BGP messages. Neither system gained much actual traction outside of the design phase as far as I know. Some might suggest that a lot of time was spent debating how to do it with little actual progress or experimentation done. The current approach has echoes of those ideas with the obvious difference as you imply, it is independent from BGP. This poses some challenges to providing a complete solution, but was probably necessary for deployment and might prove useful if something other than wants to BGP uses it. John

I would consider origin validation as just one application of the system we have today. Does that sound better? John

Nothing about your BGP announcements needs to change. Through ARIN you create one or more route origin authorizations (ROAs) with your public key. ARIN can even do all the work of creating the key pair for you if you like. You might try creating test ROAs in their operational test and evaluation environment (OTE) environment to see how this process of creating a ROA works. ISPs obtain these ROAs apart and separately from the BGP system. ISPs that fetch your ROA(s) and other RPKI objects through the RPKI ecosystem, perform validation, and communicate AS origin and prefix information contained in these ROAs to BGP routers. At that point this information is used to inform the route decision process, comparing received routes with processed ROAs as part of a route import policy. > If say we have Medium ISP (AS1000) -> Large ISP (AS200) in the above > case AS200 know it's peering with AS1000 so it will take all > advertisements.

In a nutshell, today, ISPs will only be able to validate the prefix and origin AS you publish in the ROA, this is known as route origin validation (ROV). Today someone could advertise your prefix and post-pend your AS to appear as the origin. People are working madly on solutions to protecting other parts of the BGP route attributes the origin AS, but nothing is currently, widely deployed to provide that protection with the RPKI today.

RPKI for dummies
by Dovid Bender 23 Aug '20

23 Aug '20

Hi, I am sorry for the n00b question. Can someone help point me in the right direction to understand how RPKI works? I understand that from my side that I create a key, submit the public portion to ARIN and then send a signed request to ARIN asking them to publish it. How do ISP's that receive my advertisement (either directly from me, meaning my upstreams or my upstreams upstream) verify against the cert that the advertisement is coming from me? If say we have Medium ISP (AS1000) -> Large ISP (AS200) in the above case AS200 know it's peering with AS1000 so it will take all advertisements. What's stopping AS1000 from adding a router to their network to impersonate me, make it look like I am peering with them and then they re-advertise the path to Large ISP? Again sorry for the n00b question, I am trying to make sense of how it works. TIA. Dovid

Tired of receiving spam from these jamokes. https://www.atmarktrade.com/ Atmark Trading out of Chicago. Have tried unsubscribing numerous times; e-mailed their "info" accounts to no avail. My only recourse, now, is to shame. Doubt it will do any good, but if anyone has a contact who can actually get us off their ridiculous mailing-list -- 3 to 4 e-mails a day --, well, I'm all ears. If not, well, don't do business with these bozos. /rant Happy Weekend ...
