You have two links between R1 and R2. One link connects over frame relay via OSPF Area 0. The other link is a dedicated PPP link that rides over area 45. The PPP link will primarily be the backup of the Frame Relay circuit between R1 and R2. How would you configure this network to keep OSPF operational over the PPP link when the Frame Relay circuit is down

Hello, Chamara.
Why not to put PPP link into area 0 as well?
What about virtual-link over area 45?

yes my thought also virtual link solution. I have seen this on the web and I thought to put it for a discussion, which will help to others.
thanks

You need to provide more information on the design of your OSPF network. Which other routers and areas are involved.
Intra area routes are always preferred over inter area routes regardless of metric. How much bandwidth does each interface have? Have you set the bandwidth on the interfaces to reflect this? Then OSPF would be able to calculate the best path based on that.
