Hi all! This is my first post so be patient with me! I have to design a network given IPs 146.124.0.0/16 and 146.124.10.0/24. My given requirements are : at least 60 more subnets (total 63) and maximum 1000 hosts per subnet and use of RIP. I have 3 routers (RA1, RA2, RA3) and 3 subnets (Sales, Logistic and Deposit). Given that I need 60 subs and 1000 hosts per sub, I used 146.124.0.0/16 for my subs. IP 146.124.10.0/24 cannot give me these requirements cause it has only 8 bits for subnet id and host id. So, I used this IP for my WANs, split it in subnets, and used one for each WAN. So I have : WAN 1 : 146.124.10.0/30 WAN 2 : 146.124.10.4/30 WAN 3 : 146.124.10.8/30 and LAN 1 : 146.124.212.0/22 LAN 2 : 146.124.216.0/22 LAN 3 : 146.124.220.0/22 My problem is that RIP doesn't work. I am sure that the problem is on addressing. I tried the exact same problem with different IPs and it works fine! Can someone help me??? pleaseeeeeee..........
