Tutorial No 9 Implementing Standard ACL.

 Standard ACL.

Hello guys, How you doing, Hope you all are good.

Today i'm going to take out ACL that is standard and extended. I will be teaching that in two separate tutorials. let's take standard ACL first. This topology represents a simple network using three routers.  Traffic from a specific host will be filtered.

      

Well, i m using networks of my choice you can use your's. this is just a topology.                        

• Assign IP address to every device.
• Let’s Ping all pc with each other to see whether created topology works fine.
• PC0-PC1

                     

• PCO-PC3

           

• Ping request is successfull that means network is ok. Let’s create ACL Now that will deny all packets from PC 1 from reaching all hosts in the 192.168.1.0/24 network but allow all other connectivity. I’m using “1" as the ACL number.  And then I applied the ACL to Router0, at interface fa 0/0. Well if you want to restrict any other network then just go to the gateway of the network or at the interface from where traffic is entering into that specific network and on that interface apply your ACL.
• Commands:

·         access-list 1 deny host 192.168.2.2

·         access-list 1 permit any

• Verifying ACL.

Pinging from PC0 –PC1

              

Request for ping has failed that means that standard ACL is successfully implemented. Thank you for Visit. If you like it then don't forget to comment and share. if you need this topology mention your id i will send it to you.
