Dialer watch is "watching" for the primary route to reappear in the
routing table. If after the ISDN kicks in a more preferred route enters
the routing table, dialer watch isn't going to be able to drop the line.

Subject: Dial Watch, ISDN not going down
Is there any requirement that the watched router has to be in the same
area
as the ISDN link ? How does dial watch know that it is the right route
that
is back ?
R1 ----- area 0 ISDN -----R2----|
| | LAN area 2
|------- area 0 frame--------R3-x-|
r2 watch lo0 on R3. Shut down eth0 on R3. R2 loses watched route. Brings
up
ISDN. Gets watched route via ISDN and area 0.
When eth0 on R3 is restored. R2 does not prefer the route from area 2
and
ISDN stays up.
If I put all links/routers in area 0 is works, ISDN goes down when watch
route is restored.
Is this normal ? or did I make an unsupported network topology ?
