Static Route to Provide Network Connectivity between each PC

This lab is focusing on basic Static Route, Vlan, Telnet, used to connect all network together in order to provide network connectivity between each PC (refer to the network topology), telnet to relevant equipment.

Material:

1.Two 1841 Cisco Routers
2.Four 2950-24 Cisco Switch
3.Four PC

Requirement:

1.All PC can ping each other
2.PC1 and PC3 can Telnet R1 and R2
3.All Switch (Sw-1, Sw-2, Sw-3 and Sw-4) can Telnet R1 and R2
4.Sw-1 can ping Sw-2 and Sw-3 can ping Sw-4

Network Topology:

1.All PC can ping each other

###Assign all IP Address on all PC###

Mask: 255.255.255.0 (/24)
Gateway: 192.168.10.1
Vlan: 10 (name: Admin-1)

***PC2:

After finish these part, all PC can ping its own gateway, but still not yet able to ping each other. Checking ping testing below:

Both of PC1 & PC3 can ping its own gateway, But cannot ping each other.

To make connection between each PC, we need to do routing by using Static Route in this lab as below:

***For R1:

R1(config)#ip route 10.1.1.0 255.255.255.0 209.165.200.226
R1(config)#ip route 10.1.2.0 255.255.255.0 209.165.200.226

or

R1(config)#ip route 10.1.1.0 255.255.255.0 serial 0/1/0
R1(config)#ip route 10.1.2.0 255.255.255.0 serial 0/1/0

***For R2:

R2(config)#ip route 192.168.10.0 255.255.255.0 209.165.200.225
R2(config)#ip route 192.168.11.0 255.255.255.0 209.165.200.225
 

or

R2(config)#ip route 192.168.10.0 255.255.255.0 serial 0/1/0
R2(config)#ip route 192.168.11.0 255.255.255.0 serial 0/1/0

After finish routing above, we check the result again:

 
2.PC1 and PC3 can Telnet R1 and R2

***R1:

R1(config)#enable password cisco

R1(config)#line vty 0 4
R1(config-line)#password 123
R1(config-line)#transport input all
R1(config-line)#access-class 10 in

R1(config)#access-list 10 permit host 192.168.10.2
R1(config)#access-list 10 permit host 10.1.1.2
R1(config)#access-list 10 deny any (optional)

***R2:

R2(config)#enable password cisco

R2(config)#line vty 0 4
R2(config-line)#password 123
R2(config-line)#transport input all
R2(config-line)#access-class 10 in

R2(config-line)#access-list 10 permit host 192.168.10.2
R2(config)#access-list 10 permit host 10.1.1.2
R2(config)#access-list 10 deny any

Testing Result:

***PC1

C:\>telnet 192.168.10.1
Trying 192.168.10.1 ...Open
User Access Verification
Password:

***PC3
C:\>telnet 192.168.10.1
Trying 192.168.10.1 ...Open
User Access Verification
Password:

***PC2

C:\>telnet 192.168.11.1
Trying 192.168.11.1 ...
% Connection refused by remote host

***PC4

C:\>telnet 192.168.11.1
Trying 192.168.11.1 ...
% Connection refused by remote host

3.Sw-1 can ping Sw-2 and Sw-3 can ping Sw-4

To make connectivity between each switch, we need to assign ip address and vlan on switch as below:

Sw-1(config)#int vlan 10
Sw-1(config-if)#ip address 192.168.10.254 255.255.255.0
Sw-1(config)#ip default-gateway 192.168.10.1

Sw-2(config)#int vlan 20
Sw-2(config-if)#ip address 192.168.11.254 255.255.255.0
Sw-2(config)#ip default-gateway 192.168.10.1

Sw-3(config)#int vlan 30
Sw-3(config-if)#ip address 10.1.1.254 255.255.255.0
Sw-3(config)#ip default-gateway 10.1.1.1

Sw-4(config)#int vlan 40
Sw-4(config-if)#ip address 10.1.2.254 255.255.255.0
Sw-4(config)#ip default-gateway 10.1.1.1

****Testing Result:

Sw-1 ping Sw-2

Sw-1>ping 192.168.11.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.11.254, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms

Sw-3 ping Sw-4

Sw-3>ping 10.1.2.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.2.254, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms

​​​​​​​4.All Switch (Sw-1, Sw-2, Sw-3 and Sw-4) can Telnet R1 and R2

We need to allow access on the acl as below:

R1:

R1(config)#access-list 10 permit host 192.168.10.254
R1(config)#access-list 10 permit host 192.168.11.254
R1(config)#access-list 10 permit host 10.1.1.254
R1(config)#access-list 10 permit host 10.1.2.254

R2

R2(config)#access-list 10 permit host 192.168.10.254
R2(config)#access-list 10 permit host 192.168.11.254
R2(config)#access-list 10 permit host 10.1.1.254
R2(config)#access-list 10 permit host 10.1.2.254

Testing (ex. Sw-1):

Sw-1 telnet to R1

Sw-1#telnet 192.168.10.1
Trying 192.168.10.1 ...Open
User Access Verification
Password:

Sw-1 telnet to R2

Sw-1#telnet 10.1.1.1
Trying 10.1.1.1 ...Open
