  1. Hi Rene,
    So we call DMVPN is Dynamic mGRE alternatively , rignt ??

    One more confusion regarding the output …

    Spoke1#show ip route rip 
    
          1.0.0.0/32 is subnetted, 1 subnets
    R        1.1.1.1 [120/1] via 172.16.123.1, 00:00:10, Tunnel0
          3.0.0.0/32 is subnetted, 1 subnets
    R        3.3.3.3 [120/2] via 172.16.123.3, 00:00:10, Tunnel0

  2. Hi,

    In one of last capture images, the lesson says : “Above you can see the NBMA addresses”. That is said about loopback adresses 2.2.2.2 and 3.3.3.3 that are attached to Spoke-1 and Spoke-2 routers.

    In the context of NHRP, could we say that NBMA does mean the same thing as the whole underlay network (including all “public” networks learned by the Spoke) ?

  3. Hello Tariq

    It seems that others are having similar issues with the ip summary address command when using the RIP protocol. Even so, the solution is not the default-information originate command.

    These two commands do different things.

    Default-information originate will advertise default route, while ip summary-address rip 0.0.0.0 0.0.0.0 will advertise only default route and will hide topology details. Remember that the ip summary-address command can use a more specific route, such as ip summary-address rip 10.2.0.0 255.255.0.0, it does not have to be 0.0.0

  4. Hello Laz,

    Thank you for the feedback, however I decided to simulate again with a vIOS and I received the summary-address as expected, so I guess the issue might be a bug on the initial IOS I was using which was the IOS 15.2 on a 7200.

    regards,

    Tariq
