Standard access Control List (ACL)

First, the experimental environment

GNS3 simulation software, VMware workstation software

Second, the experimental topology and IP address planning

Third, the experimental needs

PC1 can ping 192.168.5.1, but can not ping through 192.168.4.2

Iv. Steps of the experiment

1. Basic configuration on the router

The IP address on the R1 and the configuration of the routing table

The IP address on the R2 and the configuration of the routing table

2. Use the ping command to verify that the network is interoperable

3. Configure access control lists (ACLs) for network requirements

4. Use the ping command to verify that the ACL is in effect
