I know it's an old thread, but still you find it among top 3 on Google, so here's a little update to it.

You can take different aproaches on creating a navigation with a "highlighting class" with Symfony.

1. Check route
As @Sebastian J suggested, you can check with an if else for the route.

Problem: It's not officially supported, as @netmikey pointed out: How to get current route in Symfony 2?

1.1. Check route array
I actually use this on my projects, with one adjustment. I use an in array function, to be able to give more than one route.

1.2. Check route start with ...
A third approach would be what @bernland has suggested. Let's asume we want to match all routes starting with foo_products and we'd like to apply this by magic.

As I said, I use this and haven't had an issue, yet.

2. Use a Bundle/function I'm sure there are other Bundles out there, but I'd recomend you this to create your navigation: https://github.com/KnpLabs/KnpMenuBundle

3. Use a macro edit July 2015
My new favorite is to use a macro like

{% macro menuItem(name, url, subitems) %}
    {% spaceless %}
        {% set subitems = subitems|default({}) %}
        {% set currentUrl = path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')) %}
        {% set isActive = currentUrl == url %}

        {% for name, suburl in subitems %}
            {% set isActive = not isActive and currentUrl == suburl %}
        {% endfor %}

        
             0 %} class="has-sub-menu"{% endif %}>{{ name|trans() }}
            {% if subitems|length > 0 %}
                

                    {% for name, url in subitems %}
                        {{ _self.menuItem(name, url) }}
                    {% endfor %}
                
            {% endif %}
