I'm obviously not familiar with the lab product you are referring to ;-) So
what is the exact problem that was created with the /32s?

Brian,

In a CCIE lab environment, if one is instructed to use point-to-multipoint,
assume also advertise some loopback interfaces in a hub router, and as well
as each of the spoke routers. Then, would would the best choice to get rid
of /32 routes since they can create a problem for the ISDN between the hub
router and the other end connected to some other router. I have seen these
issues when I practiced some labs from IPexpert, but never got any good
answer.

Regards,

Ahmed.

Brian,

What are the possible reachability issues here.
Can you give an example. how without the /32 it would not function
correctly. I always,when shown an example understand much clearer, as I
assume most people do.

Kind regards.
Paul.
