NSSA (Not So Stubby Area) is stub Area which can transmit the routing information to 
Area by ASBR. On the other hand, Stub Area cannot transmit the routing information to 
area. To configure NSSA, use the following command. 

 <0-4294967295> nssa Router 

Configures 

NSSA. 

 

The following options are configurable for NSSA: 

•

 

 

 

This option is configuration for allowing default path of Type-7 in NSSA. It means 

 

routing path without routing information will use the interface which is allowed in de-

 

fault type-7 path. metric is for metric value, metric-type is for type of finding the path. 

 

uses internal path cost with external path cost as a cost, metric type 2 

always uses external cost value only. 

•

 

 

 This 

option is configuration in NSSA for restriction to retransmit the routing informa-

 

tion which is from outside. 

•

 

 

 This 

option is for restriction to exchange routing information between OSPF areas. 

•

 

 

 

NSSA-LSA (Link State Advertisement) has three types according to the way of 

 process 

type. 

 changes all NSSA-LSA into Type-5 LSA. candidate changes 

 

NSSA-LSA into Type-5 LSA when it is translator. never does not change NSSA-LSA. 

 

NSSA uses ASBR when it transmits Stub Area or other routing protocol Area into OSPF. 
In this case, if other routing protocol has default path, use default-information-originate 
command to configure the all of default path is using the assigned ASBR 

To configure NSSA with various features, use command with options. area  <0-
4294967295>  NSSA command has 4 options as default-information-originate,  no-
redistribution

, no-summary, translator-role and it can be selected more than 2 options 

without order. default-information-originate has metric <0-16777214> and metric-type 
<1-2> as an option, translator-role must choose one of candidate, never, always as an 
options

. 

The following is explaining options of command:
