Usually, if an import filter rejects a route, the route is
forgotten. When this option is active, rejected routes are
forgotten. When this option is active, these routes are
kept in the routing table, but they are hidden and not
propagated to other protocols. But it is possible to show them
using <cf/show route rejected/. Note that this option does not
using <cf/show route filtered/. Note that this option does not
work for the pipe protocol. Default: off.
