I bet you that the prefixes in bgpctl show rib output are not valid (marked with a *) and therefore not selected (marked with a >) and so not put into the rib. Make sure that the nexthops are valid. "bgpctl show next" should give you a list of nexthops and will also tell you if they are valid. 'bgpctl show fib next' will tell you which routes are used to validate the nexthops and will again tell you if those are valid. In short if the nexthop is not valid then the route is not valid and therfore the route is not selectable and not imported into the FIB. -- :wq Claudio
