advertisement, in the range 0 to 4294967295. The default is 1. 

cost cost: Specifies the cost of the summary route, in the range 1 to 16777214. For Type-1 external 

routes, the cost defaults to the largest cost among routes that are summarized. For Type-2 external 

routes, the cost defaults to the largest cost among routes that are summarized plus 1. 

Use the asbr-summary command to configure a summary route. 

Use the undo asbr-summary command to remove a summary route.  

No ASBR route summarization is configured by default. 

With the asbr-summary command configured on an ASBR, it summarizes redistributed routes that fall 

into the specified address range into a single route. If the ASBR resides in an NSSA area, it advertises 

the summary route in a Type-7 LSA into the area. 

With the asbr-summary command configured on an NSSA ABR, it summarizes routes described by 

Type-5 LSAs translated from Type-7 LSAs into a single route and advertises the summary route to other 

areas. This command does not take effect on non NSSA ABRs. 

With the undo asbr-summary command used, summarized routes will be advertised. 

Related command: display ospf asbr-summary.
