France was effectively contained by strong neighboring powers.

Explanation:

The results of the Congress of Viena created a new European landscape.

Delegates caused a reconfiguration of European geopolitical system:

Since European powers wanted to reset back to pre Napoleonic times, the goal of containing France was to restore the old limits and resize the distribution of land so they could create a way of balancing each other and remain in peace.

Metternich was one of the key delegates: he wanted to avoid future wars with France, so he restored power back to Europe's royal families and France was forced to return the territories it once gained from Napoleon in 1795, till 1810.

This meant that Russia increased its influence over Poland and Finland.

In the case of the Austrians, their power was limited in order to preserve peace.
