⚙️ Step 1: Create the Network Topology

In Cisco Packet Tracer:

·       Add two routers (Router0, Router1)

·       Add two PCs (PC0, PC1)

·       Connect Router0–Router1 using a Serial DCE cable

·       Connect each PC to its router with FastEthernet cables

🌐 Step 2: Assign IP Addresses

Device	Interface	IP Address	Subnet Mask
Router0	FastEthernet0/0	192.168.1.1	255.255.255.0
Router0	Serial0/0/0	10.0.0.1	255.255.255.252
Router1	Serial0/0/0	10.0.0.2	255.255.255.252
Router1	FastEthernet0/0	192.168.2.1	255.255.255.0

💻 Step 3: Configure Both Routers

Router0

enable

conf t

int fa0/0

ip add 192.168.1.1 255.255.255.0

no shut

int s0/0/0

ip add 10.0.0.1 255.255.255.252

clock rate 64000

no shut

ip route 192.168.2.0 255.255.255.0 10.0.0.2

Router1

enable

conf t

int fa0/0

ip add 192.168.2.1 255.255.255.0

no shut

int s0/0/0

ip add 10.0.0.2 255.255.255.252

no shut

ip route 192.168.1.0 255.255.255.0 10.0.0.1

✅ Step 4: Test the Connection

From PC0, ping 192.168.2.1. If successful, your routers are connected and routing properly!
