can someone help how to select the route manually

Configure OSPF Area 0 on all routers. and make the end to end connectivity.

R5 to R2 is our Lease line link

**********************************

Set the traffic like this

**********************************************

when you do the traceroute from R1 to R2 Loopback Address 147.147.11.98 ,

it should be travel through R1 to R4 to R5 to R2 and

when you do traceroute from R5 to R2 router

It travels through R5 to R4 to R1 to R3 to R2

how to give costing from R1 to R2 

and R5 to R2 to travel like below 

1-traceroute from R1 to R2 Loopback Address 147.147.11.98 ,

it should be travel through R1 to R4 to R5 to R2.

2-when you do traceroute from R5 to R2 router

It should travels through R5 to R4 to R1 to R3 to R2

[balaji.bandi]

yes you can do with Traffic engineering by manipulating the COST

show ip route (show you what is the cost in the path,)

[sivared0001]

i am not supposed to do MPLS in my level, so if it is costing then i can only solve either 1st one or 2nd one.

if i increase the cost of R1 interface that is connected to R3 that means 1st solved. and 2nd not solved.

if i increase the cost of R5 interface that is connected to R2 that means 2nd solved but 1st not choose the route that i supposed to give.

i can solve with costing only one task out of two tasks.

1-traceroute from R1 to R2 Loopback Address 147.147.11.98 ,

it should be travel through R1 to R4 to R5 to R2.

2-when you do traceroute from R5 to R2 router

[MHM Cisco World]

this is so advance OSPF case and as @balaji.bandi  mention this solve by only TE,

Hi

 You can not select a route manually and packettracer does not support source interface for ping or trace route.

But, according to your requirements:

1-traceroute from R1 to R2 Loopback Address 147.147.11.98 ,

it should be travel through R1 to R4 to R5 to R2.

2-when you do traceroute from R5 to R2 router

It should travels through R5 to R4 to R1 to R3 to R2

"It should travels" which means, if you did everything right , it should go to the right path.

i am using gns3 virtual machine.

i gave all commands in the question and if i do that it choose less distance 

in 1st task it choose from R1 to R3 to R2 

in 2nd task it choose from R5 to R2 l

if i use costing in interfaces i can satisfy only one task.

suppose lets assume 

if i gave cost 1 in all interfaces of all routers 

after that lets give cost 100 for the R5 interface that is connected to R2.

then if  we trace route 2nd TASK will be solved.

for 2nd TASK lets give cost 110 for the R1 interface that is connected to R3.

now second one will be solved but 1st TASK wont work 

the reason is cost. 

R5 to R2- cost =100(chooses

R5 -R4 -R1-R3-R2 cost =113

it choose less cost so we cant satisfy 2st TASK

but can satisfy 1st task because 

R1-R3-R2 cost = 110+1=111

R1-R4-R5-R2 cost = 1+1+100=102 (chooses)

if we decrease the R5 interface that is connected to R2 then the Task-2 wont work

[paul driver]

Hello
IF all interface costs and lsa types are equal.
RTR5<>RTR2 = DIRECT
RTR5<>RTR4 = DIRECT
RTR5<>RTR3 = via RTR2

RTR1<>RTR3 = DIRECT
RTR1<>RTR4 = DIRECT
RTR1<>RTR2 = via RTR3

RTR4<>R2/R3 = ECMP oldest lsa age

So to manually manipulate the above apply ospf interface costs would be applicable (highest values less preferred)

how to satisfy both

I must have missed these tasks? however as i stated previous all thing being equal these should be met given the topology from your OP

RTR5<>RTR2 = DIRECT < task 2
RTR5<>RTR4 = DIRECT
RTR5<>RTR3 = via RTR2

RTR1<>RTR3 = DIRECT
RTR1<>RTR4 = DIRECT
RTR1<>RTR2 = via RTR3  < task 1

RTR4<>R2/R3 = ECMP oldest lsa age

[sivared0001]

TASK1-traceroute from R1 to R2 Loopback2 Address 147.147.11.98 ,

it should be travel through R1 to R4 to R5 to R2.

TASK2-when you do traceroute from R5 to R2 router address that connected to R3 (not R2 loopback 2 address)

It should travels through R5 to R4 to R1 to R3 to R2

[paul driver]

Hello
You could accomplish this possibly through Policy Based Touting with ospf costing being equal on all interfaces, however doing PBR could also create asymmetric routing for either task you apply PBR unless its applied not only on R1/R5 but also R2.

example: TASK1
RTR1<>RTR2 = via RTR3  

RTR1
access-list 100 permit ip host 1.1.1.1 host 2.2.2.2

route-map PBR_TASK1
Match ip address 100
set ip next-hop 131.131.34.83

int lo0
ip policy route-map PBR_TASK1


RTR 2
access-list 100 permit ip host 2.2.2.2 host 1.1.1.1

route-map PBR_TASK1
Match ip address 100
set ip next-hop 131.131.34.126

int lo0
ip policy route-map PBR_TASK1

example: TASK2
R5 to R4 to R1 to R3 to R2

RTR5
access-list 100 permit ip host 5.5.5.5 host 2.2.2.2

route-map PBR_TASK2
Match ip address 100
set ip next-hop 131.131.34.151

int lo0
ip policy route-map PBR_TASK2


RTR 2
access-list 101 permit ip host 2.2.2.2 host 5.5.5.5

route-map PBR_TASK2
Match ip address 101
set ip next-hop 131.131.34.138

int lo0
ip policy route-map PBR_TASK2

[sivared0001]

R1:
access-list 100 permit host 131.131.34.82 host 147.147.11.98
access-list 100 permit host 131.131.34.163 host 147.147.11.98
route-map PBR permit 10
match IP address 100
set IP next-hop 131.131.34.168    
IP local policy route-map PBR

R2:
access-list 100 permit host 147.147.11.98 host 131.131.34.163
access-list 100 permit host 147.147.11.98 host 131.131.34.82
route-map PBR permit 10
match IP address 100
set IP next-hop 131.131.34.138    
IP local policy route-map PBR

i used the above commands

PBR not working, still i am not able to send packet from r1 to r4 to r5 to r2. (this is the way i need to use)
but it using this way (r1 to r3 to r2)
