Dear friendly DB people, here is a problem I don't find easy to solve. Would you assist me in understanding the constraints? Customer has a /22 network 194.76.156.0/22 with the proper inetnum object. The inetnum objects has a mnt-by: IPHH-NOC and mnt-routes: IPHH-NOC. A route object exists but with a different maintainer: route: 194.76.156.0/22 descr: CMELCHERS-QSC-NET descr: via Plusnet origin: AS20676 mnt-by: PLUSNET-NOC <<<---- not IPHH-NOC We are now trying to create an additional route object for a different ASN: route: 194.76.156.0/22 descr: C. Melchers via MEKO-S origin: AS207630 mnt-by: IPHH-NOC <<<--- This is the maintainer in the inetnum object source: RIPE The RIPE DB refuses the update: Create FAILED: [route] 194.76.156.0/24AS207630 route: 194.76.156.0/24 descr: C. Melchers via MEKO-S descr: belongs to 194.76.156.0/22 origin: AS207630 mnt-by: IPHH-NOC source: RIPE ***Error: Authorisation for [route] 194.76.156.0/22AS20676 failed using "mnt-by:" not authenticated by: PLUSNET-NOC So the DB expects the maintainer from the other route object. But I don't understand why the mnt-routes in the inetnum-object doesnt give preference over the maintainer on a different route-object. Anyone who could share their honest opinion? Cheers Sascha
