Summary:

 

1. Configure R1 to perform routing for VLANs 2 and 5 (router-on-a-stick). For each sub-interface, R1 should use the first valid IP

   address from each VLAN.
2. Configure R1 as a DHCP server for VLANs 2 and 5. The DHCP server should distribute client IP addresses between

   .100 and .150 for each subnet, a DNS server of 4.2.2.2 (with a secondary 8.8.8.8), and the appropriate default gateway.

3. To test, assign PC A to the IT VLAN and PC B to the accounting VLAN. Verify (using show ip interface brief) that they

   receive an IP address via DHCP. Verify routing by pinging from PC A to PC B.
