You must create an IP-IP tunnel between two routers on your network. These two devices are
separated by 10 hops. The tunnel appears to be established, but no traffic is traversing the tunnel.
What causes this behavior?
A.
The tunnel’s TTL has not been modified from the default value of 8.
B.
Traffic is being dropped along the path because a configured MTU is greater than the tunnel’s
MTU.
C.
A route that directs traffic into the tunnel is not present.
D.
BGP has not been enabled between tunnel end-points.
