1- Connect two PCs to two Cisco routers as the diagram below:
PC 1
192.168.3.10/24
GW 192.168.3.1
DNS 4.2.2.2
PC 2
192.168.2.10/24
GW 192.168.2.1
DNS 4.2.2.2
Serial link speed
64Kbps
FA 0/0 or E0
192.168.3.1
FA 0/0 or E0
192.168.2.1
172.26.1.1/30
Sx/x
DTE
R1 (Client Ruter)
DCE
Sx/x
FA 0/1 or FA 1
DHCP IP
172.26.1.2/30
R2 (Internet GW)
2- Erase Router 1/2 config
CLI Commands:
Write erase
reload
3- Configure Router 1 as below
 Serial interface with IP address of 172.26.1.1/30
 Fast-Ethernet with IP address 192.168.1.1/24
1

Static route for 192.168.2.0 as below
ip route 192.168.2.0 255.255.255.0 172.26.1.2
4- Configure Router 2 as below
 Serial interface with IP address of 172.26.1.2/30
 Fast-Ethernet with IP address 192.168.2.1/24
 Static route for 192.168.1.0 as below
ip route 192.168.1.0 255.255.255.0 172.26.1.1
5- Make sure the Serial ports are up on both routers and you can ping between the
PC’s
PC1 TO R1
2
PC 1 TO PC 2
6- Copy and paste ping results, Show interface serial and show Controller, serial
counters and show ip route on both routers
R1 TO R2
