Hello! Consider the following (anonymous) example: inetnum: 192.168.137.0 - 192.168.137.255 netname: CUSTOMER-PI-NET descr: ... country: DE admin-c: CUSTOMERADMIN-RIPE tech-c: TECHC-RIPE mnt-by: MAINT-MNT status: ASSIGNED PI mnt-routes: PROV1-MNT mnt-domains: MAINT-MNT source: RIPE # Filtered % Information related to '192.168.137.0/24AS1' route: 192.168.137.0/24 descr: ... origin: AS1 mnt-by: PROV1-MNT source: RIPE # Filtered Connectivity for 192.168.137.0/24 shall be switched to PROV2 and PROV1 may be difficult to contact. It's possible for MAINT-MNT to add another mnt-routes: inetnum: 192.168.137.0 - 192.168.137.255 ... mnt-routes: PROV1-MNT mnt-routes: PROV2-MNT But is it possible for PROV2-MNT to add another route object 192.168.137.0/24AS2 without help from PROV1-MNT? I read https://www.ripe.net/info/faq/db/route-creation-IP-space-check.html that it's not possible. Can MAINT-MNT or CUSTOMERADMIN-RIPE do anything if PROV1-MNT is unavailable?
