IP Routing—Configuring Static Routes
Configuring Static Routes
You can use static routing with dynamic routing. In this case, you supplement
routes discovered through various protocols with manually added routes. You
can configure the router to advertise these routes using a routing protocol, or
you can keep the routes private. (See Chapter 15: IP Routing—Configuring
R I P, O S P F, B G P, a n d P B R in the Advanced Management and Configuration
Guide to learn how to configure a routing protocol.)
For example, you can run a routing protocol, but configure a static default
route. (See “Configuring a Default Route” on page 11-17.)
Configuring a Static Route
When you configure a static route, you must enter the following information:
■ destination address and subnet mask
■ next-hop address or forwarding interface
By default, the administrative distance for a static route is 1 and the metric 0.
You can view the kind of information the ProCurve Secure Router stores in
its routing table in Figure 11-3.
Figure 11-3. Routing Table with Static Routes
The destination address is the network address for the destination subnet. The
subnet mask indicates how long this network address is. (The ProCurve
Secure Router also allows you to enter a prefix length instead of a subnet
mask.) When the router looks for a route that matches a packet’s destination,
it only compares the bits specified by the subnet mask.
