Re: problem sending default trough ospf

I have tried them both and I have tried them one at the time... The thing
is that the default DO get put in to the database (se output below) but
do not get transfered to
the neighbor routers.. The neighbor routers do not have any filtering..

So, I have a static default.. I have tried :

Redistribute it in without using default-information originate (with and
without the allways keeword)

Using only default-information originate allways

Using both redistribute static and default-information originate (with
and without the allways keeword)

With every one of this options, I do get the default in to the ospf
database, but it does not get transfered to the other routers.

Are there any show or debug commands that shows what routes get transferd
from the database?.. My belive was the all the
database was transfered..

Please help

  Are you doing both commands at the same time? "redis static sub" and
  "default-information originate" According to cisco doc. When you have
  a STATIC DEFAULT ROUTE and you want to redistribute into OSPF, you
  must ALSO do the "default-information originate".
