3. Consider the network below. The routers run OSPF, the LAN interconnecting the routers already has IP addresses from network 10.0.0.0/8, as indicated. 75 users 85 users 20 users 10.0.0.0/8 50 users (a) Provide IP addresses for all other subnets, using a private IP address block from class B. Subnet according to Variable-Length Subnet Masking (VLSM) principles. (b) If the LAN with 75 users had to be further divided into Virtual LANS (VLANs), how would the IP addressing change? (10) (8) 1. In general-What would need to be considered to make this change? [4 marks] 2. Give an example of how LAN 75, split into two virtually separated groups, could be supplied with IP addresses. [4 marks] (c) If the routers were running RIP as routing protocol instead of OSPF, how would the IP addressing have to change? 1. In general-What would need to be considered to make this change? [2 marks] 2. Why would a change to the existing IP addressing be necessary? [2 marks] 3. Give an example of how LAN 50 could be supplied with IP addresses in this case. [2 marks] (6) 3.
