Creating a Static Route
=======================

Scenarios
---------

You can create static routes in a route table of an enterprise router.

Static routes are classified into common routes and blackhole routes. A blackhole route only has a destination and has no next hop. It drops all traffic sent to the specified destination.

Procedure
---------

#. Log in to the management console.

#. Click |image1| in the upper left corner and select the desired region and project.

#. Click **Service List** and choose **Networking** > **Enterprise Router**.

   The **Enterprise Router** homepage is displayed.

#. Search for the target enterprise router by name.
