Robert,
The answer to your first question is YES, if the task asks you to ping every
interface that is connected to the frame-relay cloud, i would definitely
create a frame-relay map to my own IP address using one of the local DLCIs,
unless the frame-relay is configured in a P2P manner, in which you can ping
any IP address as long as you have reachability to that IP address.
I personally don't agree with doing extra work, therefore i don't like using
TCL scripts, some people do and they love it. I like to direct my focus and
attention on the exam and the material and i don't like to do extra stuff.
If you are running an IGP that conveys it's routing table via Multicast or
Broadcast, you need the "broadcast" argument on the spoke as well as the
hub.
As far as IPv6, If the frame-relay is configured in a Multipoint manner and
you are using frame-relay maps, you need to have a frame-relay mapping to
the LL address.
Check the IPv6 section of the Work Book, it's explained in there with show
commands.
