  1. Why exactly is the ABR the only one in a stub area to require the “no summary” keyword?
    I lab’d it up in GNS3 and your right the others dont need it to work and be a stub area, I was just curious as to why?
    Why dont the others in the stub area require “no summary”?

  2. Rafael,
    The difference between a Stub and a Totally Stubby Area occurs only at the ABR (the ABR determines what type of LSAs to allow into the Stub / Totally Stubby area). Since from the perspective of routers within the area there is no functional difference, there was no need to have extra information which might otherwise break the routers from forming a neighbor relationship.

  3. Rene,

    Got my response to the question which I posted in the stub area page.

    Love your work, as always…

    I have learned most of my topics by watching your gns3vault & now network lesson is to the next level.

    Kudos to you for all your efforts!

  4. Hi Rene,

    Nice explanation, The Last output:

    R2#show ip route ospf 
    O*IA [110/2] via, 00:02:27, FastEthernet0/0

    Is it supposed to be output of R3. Kindly check and update. Thanks.Preformatted text

  5. In a Totally Stubby and Totally NSSA area, only the default route will be advertise as a LSA Type 3 by the ABR? No other LSA Type 3 is advertise, correct?
