    Another question on Section 4.5

    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'.

     

    Config of R2 tunnels:

    interface Tunnel4
     ip unnumbered Loopback0
     tunnel source Loopback0
     tunnel destination 34.1.4.4
     tunnel mode mpls traffic-eng
     tunnel mpls traffic-eng autoroute announce
     tunnel mpls traffic-eng priority 6 6
     tunnel mpls traffic-eng bandwidth  5000
     tunnel mpls traffic-eng path-option 1 explicit name R2-R5-R4
     tunnel mpls traffic-eng path-option 10 dynamic
     no clns route-cache
    !        
    interface Tunnel6
     ip unnumbered Loopback0
     tunnel source Loopback0
     tunnel destination 34.1.6.6
     tunnel mode mpls traffic-eng
     tunnel mpls traffic-eng autoroute announce
     tunnel mpls traffic-eng priority 7 7
     tunnel mpls traffic-eng bandwidth  4500
     tunnel mpls traffic-eng path-option 1 explicit name R2-R4-R6
     no clns route-cache
    !
    ip explicit-path name R2-R5-R4 enable
     next-address 34.1.25.5
     next-address 34.1.0.4
    !
    ip explicit-path name R2-R4-R6 enable
     next-address 34.1.24.4
     next-address 34.1.0.6

    Re: Another question on Section 4.5

    The only issue with doing thing dynamically is that should the  IGP go into a funky forwarding stat, you would be protected from that with the static mappings.
