Scenario / Background
After an update to the network, some devices were misconfigured. You have been tasked with correcting the configurations and verifying that all the PCs can access the websites, R1, switches, and other PC can access R1 using SSH.
Router R1 and all the switches have been preconfigured with the following:
- Enable password: Ciscoenpa55
- Console password: Ciscoconpa55
- Admin username and password: Admin1/Admin1pa55
Required number of hosts per subnet:
- IT: 50 hosts
- Marketing: 50 hosts
- R&D: 100 hosts
Requirements
- IT, Marketing, and R&D PCs can navigate to www.cisco.pka and www.cisco6.pka.
- IT, Marketing, and R&D PCs can SSH into R1 with the username Admin1 and encrypted password Admin1pa55.
- All PCs should be able to ping R1, S1, S2, S3, and other PCs.
