Router's IP addresses :

• Atlanta Fa 0/1 : 10.112.8.1/30
• Atlanta Fa 0/0 : 10.111.8.1/30
• New York Fa 0/0 : 10.111.8.2/30
• New York Fa 0/1 : 10.114.65.129/30
• Chicago Fa 0/1 : 10.114.65.130/30
• Chicago Fa 0/0 : 10.115.65.130/30

Instruction

This section does not provide any instructions.

In this topolgy, I believe configuring static routing to enable communication between PC0 and PC1 would be appropriate.

Hands-on Practice

Basic Configuration

First of all, setting IP addresses on each device should be done; thereafter the links between them should be also enabled.

FYI, a next hop that is directly connected is automatically added to the routing table.

For example, on Atlanta, the routing table is configured as follows:

---

Atlanta#show ip route
...
...

Gateway of last resort is not set

     10.0.0.0/22 is subnetted, 2 subnets
C       10.111.8.0 is directly connected, FastEthernet0/0
C       10.112.8.0 is directly connected, FastEthernet0/1

---

For now, let's add static routing to enable communication between Atlanta and Chicago.

Static Routing

Atlanta → Chicago

• Atlanta

Format is ip route [Destination Network Address] [Subnet Mask] [Next Hop Host Address].

---

Atlanta(config)#ip route 10.115.64.0 255.255.252.0 10.111.8.2

---

---

• New-York

---

New-York(config)#ip route 10.115.64.0 255.255.252.0 10.114.65.130

---

---

Chicago → Atlanta

• Chicago

---

Chicago(config)#ip route 10.112.8.0 255.255.252.0 10.114.65.129

---

---

• New-York

---

New-York(config)#ip route 10.112.8.0 255.255.252.0 10.111.8.1

When I caused PC0, which was assigned 10.112.8.2, to send ICMP traffic to PC1, it returned like this :
