I have been reading about the meaning of the command Default-Information originate, what I got from the explanation is:
When you configure a router under OSPF with default-information originate
then you are instructing the router to use its own default route. So it does not maintain a default learned from its neighbor.
when u add Always keyword:
then you are instructing the router to always and unconditionally use its own default route. So it does not maintain a default learned from its neighbor.
===But I am not sure in which case this command needs to be brought up
Any help ?
thanks
As you said:
<<With Stub areas, the ABR will inject a default into the Stub rather than provide a full route table>>
The same as with Totally Stubby area.
So in which case you configure :Default-Information Orginate , either with or without the Always keyword ??
