Chapter 2: IP Addressing 
Labs:
2.10.1 In this lab, you configure VLSM and test its functionality with two different routing protocols, RIPv1 and RIPv2. Finally, you use IP unnumbered in place of VLSM to further conserve addresses.
2.10.2.1 In this lab, you create an addressing scheme using variable-length subnet masking (VLSM).
2.10.2.2 In this lab, you create an addressing scheme using variable-length subnet masking (VLSM).
2.10.2.3 In this lab, you create an addressing scheme using variable-length subnet masking (VLSM).
2.10.3 In this lab, you configure a Cisco router to act as a DHCP server for clients on two separate subnets. You also use the IP helper address feature to forward DHCP requests from a remote subnet.
Interactive Labs:
2.8.3 In this lab activity you will configure SanJose2 to act as a DHCP server. Then you will configure SanJose1 to forward UDP broadcasts for DHCP requests.
Finally, you will test your configuration using a DHCP client.
