Hey Scott,
My lab is turned off @ the moment... But when I labbed this earlier with
the attached bit configured ... I was not able to generate a 0/0 route.
When I study later on, I will try this again and post configs if it
still does not work. Thanks Scott, chat soon
Andrew

Subject: Re: ISIS - set-attached-bit and set-overload-bit
The attached bit is normally set when you have an L2 connection
someplace. Then your L1 routers get this bit and generate a 0/0 to the
L1/L2 guy. If you do NOT have an L2 connection and still want to give a
default route to your L1 peers, use the "set-attached-bit"
If your lab mentions something about creating a delay on reboot where
you will make sure tables stabilize before routing (or wanting a routing
table, but making nobody ever come through you (ISIS stub routing?))
then you may consider the overload bit.
Cheers,
Scott
