 `Link` accepts the following props:

 - [`passHref`](#if-the-child-is-a-custom-component-that-wraps-an-a-tag) - Forces `Link` to send the `href` property to its child. Defaults to `false`
 - `prefetch` - Prefetch the page in the background. Defaults to `true`. Any `<Link />` that is in the viewport (initially or through scroll) will be preloaded. Pages using [Static Generation](/docs/basic-features/data-fetching.md#getstaticprops-static-generation) will preload `JSON` files with the data for faster page transitions

 ## If the route has dynamic segments
 
-There is nothing special to do when linking to a [dynamic route](/docs/routing/dynamic-routes.md) (including [catch all routes](/docs/routing/dynamic-routes.md#catch-all-routes)). However, it can become quite common and handy to use [interpolation](/docs/routing/introduction.md#linking-to-dynamic-paths) or an [URL Object](#with-url-object) to generate the link.
