Configuring static routing
Static routes are manually configured. If a network's topology is simple, you only need to configure static
routes for the network to work correctly.
Static routes cannot adapt to network topology changes. If a fault or a topological change occurs in the
network, the network administrator must modify the static routes manually.
Configuring a static route
Before you configure a static route, complete the following tasks:
•
Configure the physical parameters for related interfaces.
•
Configure the link-layer attributes for related interfaces.
•
Configure the IP addresses for related interfaces.
You can associate Track with a static route to monitor the reachability of the next hops. For more
information about Track, see
High Availability Configuration Guide
.
To configure a static route:

Method 2:

{

mask
} {
interface-type
interface-number
[

Use either method.
By default, no static route is
configured.
3.
(Optional.)
Configure the default
preference for static
routes.
ip route-static default-preference
default-preference-value
The default setting is 60.
