Mike,
Actually you should try it with the complete solution which is
to also use PPP and CHAP authentication on the ISDN connection.
Using a dialer map without a dial string will work a lot of the
times but not all of the time especially when using HDLC encapsulation.
I always recommend that a dialer map statement include the dial string.
I've gone back and included it in most of the configurations and I'll do
the same for this one.

Subject: 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.
