part-1:
Make the primary and backup path for R1 Router,
when R1 ping to R8 router, packet should be travel from
R1->R2->R4->R3->R5->R7->R8
and when R8 give the reply it use same reverse route
part-2:
Make the primary and backup path for R2 Router,

Play with Costing if you are using OSPF as IGP
ip ospf cost XX

got it,
i have some doubts,
1.do i have to give virtual links before ip ospf cost ? to establish communication from one ospf area to another ospf areas
2.can i use static routing instead of virtual links to communicate from one ospf area to another ospf areas ?

Hello,
1. Yes you will have to configure virtual links on R3->R5 and R5->R3 as well as R4->R6 and R6->R4
Side note you will need to configure OSPF cost on the physical links (transit area) of the virtual links to manipulate the routes you need the routers to take.
2. You cannot use static routes in place of virtual links to connect area 101 to area 0
Hope that helps

In real world most use do not use Virtual Links or Sham Links, that is not best practice.
I will avoide most case using static routing

OSPF Virtual Link and transit capability.
it may solved it.
