Hello @Ab_72,
First, you'll need at least two devices: a DSL modem and a router. You can add other devices for testing, but these two are essential for a basic DSL connection.
Connect one end of router's cable to one of the Ethernet ports (e.g., FastEthernet) on the DSL modem.
Router's basic cinfiguration:
interface FastEthernet0/0
ip address 192.168.1.1 255.255.255.0
no shutdown
!
ip dhcp excluded-address 192.168.1.1
ip dhcp pool DSL_POOL
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
!
--This configuration assigns an IP address to the router's FastEthernet interface and sets up a basic DHCP pool for the DSL connection.
Configure now DSL Modem. This configuration may vary depending on the specific DSL modem model you're simulating. In a real-world scenario, DSL modems are usually provided and configured by the ISP.
Note that in PT, the DSL modem configuration might be limited or not available, so you can typically leave it as is.
Test from router: #ping 8.8.8.8
