IE Lab 10 task 5.19 - 5.21 not forming ISIS adj over ISDN

  I had a problem when trying to test my configuration for task 5.19 - 5.21
on lab 10. I had my configuration which is below the same as the solutions
guide and was unable to for an adjacency over the ISDN line when R4 lost its
Frame relay connection to R3. The problem I saw was that R5 was having layer
3 to layer 2 mapping issues. When I changed the mapping statement on R5 to
 dialer map clns 28.0001.0001.0004.00 broadcast 8358661 the adjacency formed
properly. Was this a misprint in the solutions guide or am I missing
something in my config ?

   Thanks,

      Mike F.
