 should be "out FROM" in this sentence..... Usage Guidelines

When redistributing networks, a routing process name can be specified as an
optional trailing argument to the *distribute-list* command. Specifying an
argument causes the access list or prefix list to be applied to only *those
routes derived from the specified routing process*.
