distance (OSPF)

Configures an administrative distance value for OSPF routes.

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

no distance

Operands 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.

Defaults The administrative distance value for OSPF routes is 110.

Command Modes OSPF VRF router configuration mode

Description Use this command to specify the administrative distance for different OSPF route types. 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 OSPF intra-area route is always preferred over an OSPF

inter-area route, even if the intra-area route’s distance is greater than the inter-area route’s

distance.

Usage Guidelines Enter no distance to return to the default setting.

Examples To set the distance value for all external routes to 125:

switch# configure

switch(config)# rbridge-id 5

switch(config-rbridge-id-5)#router ospf

switch(config-router-ospf-vrf-default-vrf)# distance external 125
