destination host unreachable  = this means the next hop or end device do not know how to reach the destination.

traceroute helps you, where it stops, that is the device you need to investigate the routing.

Rather instruction manual,. you need to provide the configuration you have done on your lab

post below information from all devices :

show run

show IP route

show IP interface brief

as i see your config Router 1 and Router 2 have same IP address on the interface, which conflicts in the network

change to un used IP address and test it.

When you say “have the same ip address on the interface. Do you mean serial interface or the network such as. 

ip dhcp pool asia

network 192.168.2.0 255.255.255.0

i have changed the serial ports already so now each serial port has a different ip

Please specify where the ip address needs to be changed 

router 1=

FastEthernet0/0 192.168.2.1 YES manual up up

Serial2/0 10.0.0.2 YES manual up up

Serial3/0 10.0.1.2 YES manual up up

Router2=

Interface IP-Address OK? Method Status Protocol

FastEthernet0/0 192.168.2.1 YES manual up up

Serial2/0 10.0.0.2 YES manual up up

Serial3/0 10.0.1.2 YES manual up up

 

If you have changed this above post new config as below

show run

show IP interface brief

show cdp neigh

show IP arp
