Note :- R1 and R3 have only one exit interface, default Router will advertise only on R1 and R3
Task 1 :- Configure IP Address according topology
Task 2 :- Configure loopback Address according topology
Task 3 :- Configure Static Route on R2 , give Default Route on R1 and R3
Task 4 :- check the reachability between R1 to R3 loopback
