As we see the network 20.20.20.0/24 is not there
I can do in two ways:
- Static routing
- Dynamic routing
RIP
OSPF
EIGRP
v Now we will do the static route
Hint: you need to put the destination network inside my routing table
Do as follow:
R1#config t
R1(config)#ip route 20.20.20.0 ? 255.255.255.0 ? 30.30.30.6
destination Subnet next hop ip address
On R2 you do same concept but reverse:
R2#config t
(config )#ip route 10.10.10.0 255.255.255.0 ? s0/3/0
Destination mask (your own inter)
Here is my config for R1:
R1#config t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#ip route ?
A.B.C.D Destination prefix
R1(config)#ip route 20.20.20.0 ?
A.B.C.D Destination prefix mask
R1(config)#ip route 20.20.20.0 255.255.255.0 ?

R1(config)#ip route 20.20.20.0 255.255.255.0 30.30.30.6 ?
<1-255> Distance metric for this route
<cr>
R1(config)#ip route 20.20.20.0 255.255.255.0 30.30.30.6
R1(config)#
Here is my show run:
R1#show run
ip route 20.20.20.0 255.255.255.0 30.30.30.6
Now I will do at R2 but i use my own interface:
Remember ping is:
Echo
and echo reply it must go and come back
Here is my config for R2
r2#show ip route

Now I should be able to ping from Pc1 to pc4:
PC>ping 20.20.20.4
Pinging 20.20.20.4 with 32 bytes of data:

In order pc1=10.10.10.1 be able ping 20.20.20.4 ; the network
20.20.20.0/24 must be inside the routing tables; if it is not
i can put there in different way
