Section 4.5 states that the Tunnel between R2 and R4 should use the frame-relay link should the connection to R5 go down. So, I simply set up a dynamic tunnel as path option 10 and my explicit path with option 1.
Would this meet the requirements of that section? The solution guide has the R2 to R4 tunnel set up with two explicit paths.
I tested it and the dynamic tunnel used the frame-relay link as soon as I shut down the connection to R5.
Is there something in the wording of the question that I missed? Or, am I 'good to go'.
