  In this lab, I am gonna teach you   OSPF Multi Area Configuration of 4 Routers Given Network: 192.168.0.0 Required hosts on Router 1= 100 Required hosts on Router 2= 30 Required hosts on Router 3= 6 Required hosts on Router 4= 1 R1<= 100 100<= 2 n  – 2 100<= 2 7  – 2 100<= 128 – 2 100<= 126 Total number of network bits = 32 32 – n = 32 – 7 = 25  (CIDR value of given network i.e. Router 1) i.e. 192.168.0.0/25 N.S.M = 11111111. 11111111. 11111111.10000000                         = 255.255.255.128 Block Size       = 256 – N.S.M                         = 256 – 128 = 128 Note: Add this block size in given network so that we can get our new network for Router 2. So the new network is 192.168.0.128/? N...
