hi danny,
yes you do need a "no peer neighbor-route" but only if u are running a
distnce vector on one of the ISDN routers (not necessarily on the ISDN
interface but any interface on that router)....or else there is no need of
this command....distance vector always creates a host route. in an ISDN
situation it causes the link to flap.Theres a whole big example on this on
the cisco site.will post the link soon.
OSPF deman circuit can be configured either side....not a problem.
It will negotiate and it just supresses the hello's....nothing else.
cheers,
sumit
