Question 1


The topology of DMVPN is always hub-and-spoke as all Spokes are required to connect to the Hub router directly.

    Q2. I agree that C and D are two valid answers but is B ? If the tunnel interface is down, it think it would be in the down/down state.

    Presumably if the tunnel interface IP address is misconfigured then the tunnel interface will be up/down – which would mean that answer A is correct ?

    In regards of Q2, I found following explanation:

    Line Protocol Down Locally on the Router

    Under normal circumstances, there are only three reasons for a GRE tunnel to be in the up/down state:
    There is no route, which includes the default route, to the tunnel destination address.
    The interface that anchors the tunnel source is down.
    The route to the tunnel destination address is through the tunnel itself, which results in recursion.
    These three rules (missing route, interface down, and misrouted tunnel destination) are problems local to the router at the tunnel endpoints and do not cover problems in the intervening network or other features related to the GRE tunnel that might be configured. This document describes scenarios where other factors might influence the state of the GRE tunnel.
