distance (OSPF)

Configures an administrative distance value for OSPFv2 and OSPFv3 routes.

Syntax

distance { external | inter-area | intra-area } distance

no distance

Command Default

The administrative distance value for OSPFv2 and OSPFv3 routes is 110.

Parameters

external: Sets the distance for routes learned by redistribution from other routing domains.
inter-area: Sets the distance for all routes from one area to another area.
intra-area: Sets the distance for all routes within an area.
distance: Administrative distance value assigned to OSPF routes. Valid values range from 1 through 255. The default is 110.

Modes

OSPF router configuration mode

OSPFv3 router configuration mode

OSPF router VRF configuration mode

OSPFv3 router VRF configuration mode

Usage Guidelines

You can configure a unique administrative distance for each type of OSPF route.

The distances you specify influence the choice of routes when the device has multiple routes from different protocols for the same network. The device prefers the route with the lower administrative distance. However, an OSPFv2 or OSPFv3 intra-area route is always preferred over an OSPFv2 or OSPFv3 inter-area route, even if the intra-area route‘s distance is greater than the inter-area route‘s distance.

The no form of the commands reverts to the default setting.

Examples

The following example sets the distance value for all external routes to 125.

device# configure terminal
device(config)# router ospf
device(config-router-ospf-vrf-default-vrf)# distance external 125

The following example sets the distance value for intra-area routes to 80.

device# configure terminal
device(config)# router ospf
device(config-router-ospf-vrf-default-vrf)# distance intra-area 80

The following example sets the distance value for inter-area routes to 90.

device# configure terminal
device(config)# ipv6 router ospf
device(config-ipv6-router-ospf-vrf-default-vrf)# distance inter-area 90
