To scroll down to your anchor tags, you need to install React Router Hash Link, with:
npm install --save react-router-hash-link
then import Hash Link:
import { HashLink as Link } from 'react-router-hash-link';
and then use Hash Link, for example:
<Link to="/pathLink#yourAnchorTag">Your link text</Link>
and at the destination component, for example:
<div id= "yourAnchorTag">
<p>Linked to here<p>
</div>
