OSPF Routing?

[imran_mcse]

When we are configuring OSPF routing for network 1.1.1.1/24 we can type:

R1(config-router)#network 1.1.1.0 0.0.0.255 area 0

And

R1(config-router)#network 1.1.1.1 0.0.0.0 area 0

What is difference between these two commands? Pls explain.

network 1.1.1.0 0.0.0.255 area 0 means that any interface in the 1.1.1.0 network will send and recieve ospf routing updates.

network 1.1.1.1 0.0.0.0 area 0 means that only the interface with IP address 1.1.1.1 will send and recieve ospf routing updates.

The first is a network of 255 IP Address while the second is a single IP Address or a host which is only 1.1.1.1
