Stub, stub no-summaries and nssa no-summaries will all generate a default
route from the ABR.
This has nothing to do with the concept of a DR. That's a per-interface
election. (At least per spec, although it's always worth a try to see if
there's weird things happening)
But I'd look at your 3550 configuration. If your 3550 has more than one
area and believes it's an ABR, then it will not install the 0/0 route. If
your 3550 is not configured as a stub area as well, then you'll lose your
adjacency (although I would think you'd notice that!).
What does the 3550 have in the OSPF database at this point? Do the things
in your routing table match up?

Hi,
The Default Route is I remember well, is only generated in Totally Stuby
Area Type (NSSA or not NSSA)
If you like to generate a default route in other area types then use the
default-information-originate

Asunto: stub areas default route and DR
All,
I was practicing on lab scenario that has an OSPF adjacency between a
router fast Ethernet interface and a vlan interface. the link between them
is the only one in the area. The switch should only get a default route from
the router and nothing else. I used the stub area no-summary command on the
router and stub area on the switch and I could not get the router to send
the default route to the switch. Then I changed the configs to be nssa
no-summary on the router and nssa on the switch and still it did not work. I
was wondering if the switch is the DR could that be a reason why it never
receives the default route?
