D . add a static route for the Tunnel0 destination IP address

Answer: D

Explanation:

The %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing error message means that the generic routing encapsulation (GRE) tunnel router has discovered a recursive routing problem. This condition is usually due to one of these causes:

+ A misconfiguration that causes the router to try to route to the tunnel destination address using the tunnel interface itself (recursive routing)

+ A temporary instability caused by route flapping elsewhere in the network So in this question maybe there is something wrong with the tunnel destination so we should add static route to solve it.
