Prompt Title: Connecting two routers

To connect two routers using a serial DCE (Data Circuit-terminating Equipment) connection in Packet Tracer, follow these steps:

1. Launch Packet Tracer: Open Packet Tracer on your computer.

2. Add Routers: Drag and drop two router devices (such as Cisco 1841 routers) onto the workspace.

3. Add Serial Interfaces: Click on each router, then click on the "CLI" tab to access the command line interface. Enter the following commands to add a serial interface and set the clock rate on one router (DCE):

graphqlCopy code
enable
configure terminal
interface serial 0/0/0   [Note: Interface numbering may vary depending on the router model]
clock rate 64000         [This sets the clock rate for the DCE connection]
no shutdown

On the second router (DTE), enter similar commands but without the clock rate command:

graphqlCopy code
enable
configure terminal
interface serial 0/0/0   [Interface numbering may vary]
no shutdown

4. Connect the Serial Cables: Click on the "Connections" tool in the sidebar, then select the "Serial" option. Click on one router's serial interface, then click on the other router's serial interface to create the connection.

5. Configure IP Addresses: Assign IP addresses to the serial interfaces on both routers. Here's an example:

javaCopy code
Router A (DCE):
interface serial 0/0/0
ip address 192.168.1.1 255.255.255.0

Router B (DTE):
interface serial 0/0/0
ip address 192.168.1.2 255.255.255.0

6. Verify Connectivity: Test the connectivity between the routers by pinging the IP address of the remote router from each router's command line interface.

That's it! You've successfully connected two routers using a serial DCE connection in Packet Tracer.
