Configuring Static Routes

19-21

Configuring Static Routes

This router can dynamically configure routes to other network segments using

dynamic routing protocols (i.e., RIP or OSPF). However, you can also manually

enter static routes in the routing table. Static routes may be required to access

network segments where dynamic routing is not supported, or can be set to force the

use of a specific route to a subnet, rather than using dynamic routing. Static routes

do not automatically change in response to changes in network topology, so you

should only configure a small number of stable routes to ensure network

accessibility.

Command Usage

• Up to 64 static routes can be configured.

• If a static route is defined, it will always take preference over a dynamic route.

• Static routes are included in RIP and OSPF updates periodically sent by the router

if this feature is enabled by the RIP or OSPF (see page 20-9 or 20-35,

respectively).

Command Attributes

• Interface – Index number of the IP interface.

• IP Address – IP address of the destination network, subnetwork, or host.

• Netmask – Network mask for the associated IP subnet. This mask identifies the

host address bits used for routing to specific subnets.

• Gateway – IP address of the next router hop used for this route.

• Metric – Cost for this interface. (Range: 1-5, Default: 1)

The metric is an administrative distance, and indicates that this route can be

overridden by dynamic routing information if the distance of the dynamic route is

less than that configured for the static route. Note that the default administrative

distances used by the dynamic unicast routing protocols is 110 for OSPF and 120

for RIP.

• Entry Count – The number of table entries.
