In this lab, we will start basic configuration and routing, then we will evaluate the use of access lists in Routers. Start by creating the topology below:

Step 1: Configure IP Address on routers. R1-Configuration

Access List Configuration Now Configure Extended ACL on router R1 so that it will block ping packets but allow others.
