React Router isn't working ; Index Route

Question

Sorry if this is a duplicate question. I can't seem to solve this or find an answer. I have a basic React Router setup that I'm trying to get working and I'm really stuck on getting IndexRoute to it's linked component. I feel like I'm missing the point on how this library works and would love some advice.

Thanks in advance.

Here's the code.

App.js

import React from 'react'
import reactDOM from 'react-dom'
import { Router, Route, hashHistory, IndexRoute } from 'react-router'
import About from "./About Us/About"
import FrontPage from "./Front Page/FrontPage"
import HeaderNavigation from './General/HeaderNavigation';


reactDOM.render((
    <Router history = {hashHistory}>
        <Route path="/" component={FrontPage}>
            <IndexRoute component = {HeaderNavigation}/>
            <Route path="/About" component={About}/>
        </Route>
    </Router>
), document.getElementById('app'));

HeaderNavigation.js

import React from 'react';
import { Nav, Navbar, NavDropdown, MenuItem, NavItem, Link } from 'react-bootstrap';


export default React.createClass ({
    render() {
        var Dlink = 'https://scontent-sjc2-1.xx.fbcdn.net/v/t1.0-9/12373357_497613000418878_5796459715901767943_n.png?oh=0484e476279b076d27eeeadc2d12b1d8&oe=590CD405'
        return (
            <Navbar>
                <Navbar.Header>
                    <Navbar.Brand>
                        <img src= {Dlink} alt="Legalink" height="6000 px"/>
                    </Navbar.Brand>
                </Navbar.Header>
                    <Nav bsStyle = "pills">
                        <NavItem eventKey = "{1}" disabled>Product</NavItem>
                        <NavItem eventKey = "{2}">Support</NavItem>
                        <NavDropdown title  ="More" eventKey = "{3}">
                            <MenuItem eventKey = "{1}">Background</MenuItem>
                            <MenuItem eventKey = "{2}">Contact Us</MenuItem>
                        </NavDropdown>

Your FrontPage.js is the main page, and all other component you are passing as child component by react-router, so you need to specify the place where you want to render your child component in FrontPage.js, you forgot to add this line:

{this.props.children}

Try this:

import React from 'react';

import Carousel from './Carousel';
import Body from './Body';

export default React.createClass({
    render() {
        return 
        <div>
            <Carousel/>
            <Body/>
            {this.props.children}
        </div>
    }
})
