RPKI Data Quality and Usage
by Carlos Martinez-Cagnazzo 25 Feb '12

25 Feb '12

Hello, This is Carlos from LACNIC. We are seeing the same poor RPKI data quality in our region and we share the same concerns that Alex has expressed. Currently our hosted system *does not* renew anything automatically. It will send automatic reminders when expiration times are near, but that's just about it. ROA upkeep is left to the users. The system does not prevent users from creating ROAs with expiry times 100 years in the future, although no one seems to ever change the default value of two years. The most common operational mistake we are seeing has to do with failure to create covering ROAs for BGP downstream customers while having too long maxLen values in the upstream ROAs. While I have personally contacted some of our members regarding the bad ROAs, we have so far met with limited success. Warm regards Carlos

Routing Working Group at RIPE 64, Ljubljana
by Rob Evans 23 Feb '12

23 Feb '12

Hi, No sooner have we washed our laundry after returning from Vienna, then it is time to start thinking about what we're going to talk about in Ljubljana towards the end of April. Or so it feels like anyway. That could just be age on my part. We are scheduled to meet after lunch on Wednesday, April 18th. If you would like to suggest any content, please email either myself, Joao, or even both of us through <routing-wg-chairs(a)ripe.net>. All the very best, Rob
