Cisco Designated VIP,
I am trying to configure an OSPF Demand Circuit between three areas connected by a virtual link. Here is the setup:
R1 (area 2) -- R2 (Area 1 Area 2) -- R3 (area 2 Area 0) -- R4 (area 0).
The virtual link is between R2 and R3. The ISDN runs between R1 and R4. My question is: when I put the network of the Dialer interfaces on R1 and R4 into OSPF, which area do they have to be part of ? Or is it a limitation of the OSPF Demand Circuit that it cannot span areas ? After all, the same network cannot be part of two areas.
Thanks for your help in advance.
