Thank you so much, it works! The route is now well seen as unknown by the cisco router: Refresh Epoch 1 206155 89.234.186.158 from 89.234.186.158 (80.67.190.204) Origin IGP, metric 50, localpref 200, valid, external, best Community: 64496:200 path 7FA510447288 RPKI State not found rx pathid: 0, tx pathid: 0x0 Thanks also for the advices on the configuration. It dates from some times ago now and has endured many modifications ;) Kind regards, -- Alarig Le Lay
