area range
SecureStack C3 Configuration Guide 20-21
Parameters
Defaults
If route type is not specified, the distance value will be applied to all OSPF routes.
Mode
Router configuration: C3 (su) ‐ >router(Config ‐ router)#
Usage
If several routes (coming from different protocols) are presented to the SecureStack C3, the
protocol with the lowest administrative distance will be chosen for route installation. By default,
OSPF administrative distance is set to 110. The distance ospf command can be used to change this
value, resetting OSPF’s route preference in relation to other routes as shown in the table below.
Example
This example shows how to change the default administrative distance for external OSPF routes to
100:
C3(su)->router(Config)#router ospf 1
C3(su)->router(Config-router)#distance ospf external 100
area range
Use this command to define the range of addresses to be used by Area Border Routers (ABRs)
when they communicate routes to other areas. Each SecureStack C3 stack can support up to 4
OSPF areas. The no form of this command stops the routes from being summarized.
Syntax
area area-id range ip-address ip-mask [ advertise | no-advertise ]
no area area-id range ip-address ip-mask
external | inter ‐
area | intra ‐ area
Applies the distance value to external (type 5 and type 7), to inter ‐ area, or to
intra ‐ area routes.
Note: The value for intra-area distance must be less than the value for
inter-area distance, which must be less than the value for external distance.
weight Specifies an administrative distance for OSPF routes. Valid values are 1 ‐
255 .
