Setting Bootstrap navbar active class in Laravel 5

I’ve been wondering around looking for solutions, but can’t really understand especially when creating helpers. I’m new in Laravel and I want a simple or if not a detailed instruction on how to set the active class for my bootstrap navbar.

Here’s what I’ve done so far, but can’t get it done:

<div class="header clearfix">
        <nav>
          <ul class="nav nav-pills pull-right">
            <li class=""><a href="{{ url('/') }}">Home</a>
            </li>
            <li {{ Request::is('about*') ? ' class="active"' : null }}><a href="{{ url('about') }}">About Us</a>
            </li>
            <li><a href="{{ url('auth/login') }}">Login</a>
            </li>
        </ul>
    </nav>
    <h2 class="">Tobacco Prevention and Control Program</h2>
</div>

EDIT

Setting class="active" will make all nav-pills active. The intended effect is that only the li of the current page have the active class.

<ul class="nav nav-second-level">
                    <li class="{{ Request::segment(1) === 'programs' ? 'active' : null }}">
                        <a href="{{ url('programs' )}}" ></i> Programs</a>
                    </li>
                    <li class="{{ Request::segment(1) === 'beneficiaries' ? 'active' : null }}">
                        <a href="{{url('beneficiaries')}}"> Beneficiaries</a>
                    </li>
                    <li class="{{ Request::segment(1) === 'indicators' ? 'active' : null }}">
                        <a href="{{url('indicators')}}"> Indicators</a>
                    </li>                     
                </ul>
