The "peer neighbor-route" command will install a host route for the other
end router once ppp is negociated. Normally this route is not needed.

I have seen several lab scenarios in which the author would configure the
"no peer neighbor-route" even when not needed. It will save you some
valuable time (and points) in the real lab if you configure it as it avoids
situations in which isdn flapping occurs,

The point is that you only NEED to have it on one side of the link because
the two routers will negotiate that and set the link on both sides as a
demand circuit and this will be reflected on the routes learnt from both
routers.

If you add it on both ends it should still work but you do not need to do
that.

Can you have the "ip ospf demand-circuit" in both sides of a BRI link? Books
that I have read say that you are only supposed to have this command in one
side of the link and I was told the same thing in the ccbootcamp I attended.

I found this document in Cisco site (Document 4808):

http://www.cisco.com/en/US/tech/tk365/tk480/technologies_tech_note09186a
0080
09481b.shtml

This document claims that you can use the "ip ospf demand-circuit" in both
sides. Does this cause problems?

Also, is it good practice to include the "no peer neighbor-route" command in
the BRI interfaces to keep redistribution from bring up the bri links.
