hey Phong,
that defeats the purpose for which hes using the "OSPF Demand Circuit"
.....backup.....in yr solution the isdn will never come up.....even if there
is a change in the backbone area.
The purpose of "demand circuit" is NOT "backup"...but to keep isdn down when
running ospf on it .....so that isdn is used only by interesting traffic.
for backup use "watch-list" or "backup interfaces".
cheers,
