Command Usage
• The command affects both static and dynam ic unica st routing.
• If IP routing is enabled, all IP packets are routed usin g either static routing or
dynamic routing via RIP or OSPF, and other packets for all non-IP pro tocols
(e.g., NetBuei, NetWare or AppleTalk) are switched based on MAC
addresses. If IP routing is disabled, all packets are switched, with filtering and
forwarding decisions based strictly on MAC addresses.
Example
Console(config)#ip routing
Console(config)#
ip route
This command configures static routes. Use the
no
form to remove static routes.
Syntax
ip route {destination-ip netmask | default} {gate way} [metric metric]
no ip route {destination-ip netmask | default | *}
• destination-ip – IP address of the destination network, sub network, or host.
• netmask - Network mask fo r th e as soci ated I P subn et . T his ma sk id ent ifies
the host address bits used for routing to specific subnets.
• default – Sets this entry as the default route.
• gateway – IP address of the gate wa y us ed for this r oute .
• metric – Selected RIP cost for this interface. (Range: 1- 5, defau lt: 1)
• * – Removes all static routing table entr ies.
Default Setting
No static routes are configured.

Global Configuration
Command Usage
• You can configure up to 64K static routes.
• If a static route is defined, it will always take preference over a dynamic rout e.
• Static routes are included in RIP and OSPF updates periodica lly sent by the
router if this feature is enabled by the RIP or OSPF

(see page 42-11 or page 42-25, respectively).
Example
This example forwards all traffic for subnet 192.168.1.0 to the router 192.1 68.5.2 54,
using the default metric of 1.
Console(config)#ip route 192.168.1.0 255.255.255.0 192.168.5.254
