    One more confusion regarding the output …

          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

  3. 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) ?

  4. Hello Maodo

    The NBMA in this particular example refers to the nature of the actual physical network, and the addressing of the physical interfaces connected to the medium. That is, the 192.168.123.X subnet. So if this is what you mean by the whole underlay network, then yes you are correct.

    I hope this has been helpful!
