15.12 distance (OSPF)

To define Open Shortest Path First (OSPF) route administrative distances based on route type, use the
distance command in router configuration mode. To restore the default value, use the no form of this
command.


Command Syntax

distance {distance | ospf [external dist1] [inter-area dist2] | [intra-area dist3]}
no distance {distance | ospf}

distance Administrative

distance.

An

integer from 1 to 255. (Routes with a

distance value of 255 are not installed in the routing table.)

external dist1

(Optional) Sets the distance for routes from other routing domains,
learned by redistribution. Range is 1 to 255. The default value is 110.

inter-area dist2

(Optional) Sets the distance for all routes from one area to another
area. Range is 1 to 255. The default value is 110.

intra-area dist3

(Optional) Sets the distance for all routes within an area. Range is 1
to 255. The default value is 110.


Default

dist1: 110
dist2: 110
dist3: 110

Usage

You may specify one of the keywords or use distance only to apply to all types of routes.
The distance command allows you to set a distance for an entire group of routes, rather than a specific
route that passes an access list.
A common reason to use the distance command is when you have multiple OSPF processes with
mutual redistribution, and you want to prefer internal routes from one over external routes from the
other.


Examples

The following example shows a router in autonomous system using both the Routing Information
Protocol (RIP) and the OSPF routing protocols. The example advertises OSPF-derived routes using
RIP and assigns the Internal Gateway Protocol (IGP)-derived routes a RIP metric of 10.
