In BGP, when implementing a route map for redistribution, it is important to ensure that all desired routes are matched and allowed as needed. By including a permit statement as the last entry of the route map, you ensure that any routes that have not been matched by earlier statements will be permitted by default. This is because route maps have an implicit deny at theend, so without a final permit statement, unmatched routes would be denied.
