[members-discuss] About "route" objects and BGP announce

Dear list, We are LIR for an organization (org1) and managing their class B. 3 AS are announcing /24 routes on this class B. We own the /16 route object. "mnt-routes" is set for org2 for a route R "mnt-routes" nothing declared for org3 I declared the ROA for org1, org2, org3. What seems strange to me is that org3 announces route R. And it works fine. Is that normal ? Regards, Gilles
