according to this document
ip summary-address rip needs split-horizon disabled,
it doesnt behave that way though.

******************************************************************
The auto-summary function is independent of the split-horizon function.
Split-horizon needs to be disabled if routes learned from one neighbor need
to be advertized to another neighbor through the same physical interface
which is the situation you have on a hub router in a frame relay hub and
spoke topology. The auto summary function has nothing to do with
split-horizon. It should be enabled or disabled based on your ip addressing
scheme. See Doyle's Routing TCP/IP volume 1 for all the details.

************************************************************
The answer to this question can't be explained in a short paragraph. I
would again suggest you see the chapter on redistribution in the above
mentioned book.

*********************************************************************
Like OSPF, in ISIS for 2 neighboring routers to form an adjacency, they both
have to have the same network type. Regardless of what routing protocol
your running, for any routing protocol to work, you'll need the F/R
interfaces properly configured. To successfully pass the lab, you'll need
to know how to configured F/R interfaces in each of the various ways
possible and get the F/R cloud working in less than 10 minutes. In other
words, you'll need to know how to configure Frame Relay so well, that you
won't even have to think about what needs to be done. Possible the best
reference <IMHO> is Caslow's book, Cisco Certification.
