Can you help me grasp the concept behind the network command. I know the command does 3 things:
broadcast the routing updates out an interface
listens for incoming updates on the same interface
advertise the subnet(s) off that interface in the routing update.
However, when you enter the router subcommand configuration mode and type "network" followed by the network number this is where I get stumped. Is this just the subnet number? If not why? What's the difference between the network number and subnet number?
Example: You have a router with 2 serial interfaces (S0 and S1), 2 Ethernet interfaces (E0 and E1), 1 Token Ring interface (T0). You want to configure the RIP routing protocol. IP Addresses are as follow:
E0 - 10.1.2.3 255.255.255.0
E1 - 172.16.1.1 255.255.255.0
T0 - 10.1.3.3 255.255.255.0
S0 - 18.104.22.168 255.255.255.0
S1 - 22.214.171.124 255.255.255.0
