Chapter 64 Configuring Routing Policies
Static Routing on Cisco IOS Routers
Static Routing on Cisco IOS Routers
You can configure static routing policies to ensure that the router correctly forwards packets to their
destination when a route cannot be built dynamically. By default, static routes have a default
administrative distance of 1 (implying a directly connected network), which causes them to override any
dynamic routes discovered for the same host or network. You can, however, define a larger
administrative distance to a static route so that it does not take precedence over a corresponding dynamic
route.
For example, EIGRP routes have a default administrative distance of 5. To have a static route that can
be overridden by an EIGRP route, you must specify an administrative distance greater than 5. This
feature is useful when you define the static route as a “floating” route, which is inserted into the routing
table only when the preferred route is unavailable.
Tip When you use the static route as a backup, “floating” route, specify the interface through which the next
hop IP address can be reached instead of entering a specific IP address. Otherwise, the “floating” route
is not inserted in the routing table if the primary link fails. For more information, see Specifying a Next
Hop IP Address for Static Routes on Cisco.com at this URL:

Defining Static Routes
To define a static route, you must define the IP address (and optionally, the metric) of the hop gateway
to which the router forwards packets destined to the selected host or network. You can define as many
static routes as required.

Step 1 Do one of the following:
• (Device view) Select Platform > Routing > Static Routing from the Policy selector.
Transparent Metric When selected, maintains the original metric of the route being
redistributed. When deselected, the value specified in the Metric field
is used.
