How to inject the default route in Totaly NSSA area in OSPF

dora_smith

I've configured on ABR "area 1 nssa no-summary", and on the Totally NSSA area's router "area 1 nssa", and I don't get any default route in my routing table. 

 

Thanks in advance!

Hello,

 

it is unclear from your post what you have configured.

 

area 1 nssa no-summary --> that means you have configured a totally stub area, which generates a summary LSA with link-state ID 0.0.0.0  (there is no need for 'default-information originate)

 

area 1 nssa --> that means you have created a NSSA and the 'area x nssa no-summary' command will generate a default route

 

Post the full running configs of both routers so we can see what you have actually configured.

In ABR you can use always with default information originate to make it inject default route even if not learn from other router in ospf areas.

What you have created sounds like a  "no-so-stubby area" and if you wanted to have default route injected into this area then you would need to specify  "area x nssa default-information originate" to do so , this area allows type 1,2,3,7 lsa's & default

However if you wish turn the NSSA into a "no-so-totally-stubby area" using the "area x nssa no-summary" then a default would be installed automatically along with only type 1,2,7 lsa's
