Why would you make the interfaces passive inside the tunnel? Isn't the
purpose of your tunnel to join the two area 0's together? If so making
the interfaces passive will mean that the routers do not become
neighbors across the tunnel and in turn you aren't joining the two area
0's together. Also you need to put the tunnel interfaces in area 0
(network statements) for this to work.
Lastly you should really step back and lab this up. Try to answer your
questions below by doing the configuration. You'll learn ten times more
by doing tasks like this.

Subject: RE: OSPF and ISDN question
Thanks Christian for your help. So basically for the
OSPF question, we need to create a tunnel between the
two routers connected to area 0. Lets say we assign
20.20.20.1 on one side of tunnel and 20.20.20.2 on the
other side. Do we need to advertise this network in
area 0. Also do we need to change the ospf cost on
tunnel by using ip ospf cost x . Also I think we need
to make the tunnel interface passive interface in OSPF
configuration.
Also is it recommended to change the ospf cost on
tunnel.
Your input will be highly appreciated.
Thanks
Azhar
