Network command

    I am using the EIGRP protocol, I have a router that has its ports with
    the following IP addresses(10.2.3.4 , 10.2.3.5 , 10.2.3.6)
    What would be better for the network command, that is used in the EIGRP
    configuration,

    (Network 10.2.3.0 )
    or the
    (Network 10.0.0.0)

    OK, now what if the port IP addresses of the router were
    (190.186.2.3 , 190.186.2.4 , 190.186.2.5)
    will it be
    (Network 190.168.2.0)
    or the
    (Network 190.0.0.0)

    Did you get my idea, I mean: should we use the smallest or the biggest
    network range inside the network command, and is there any difference
    when the network type is A, B or C.

    The network statement is used to enable EIGRP on router interfaces.

    Generally a classful network would be specified althought the EIGRP
    statement now also accepts a mask

    for example

    network 10.0.0.0 ! typical usage - all 10.x.x.x interfaces will be
    enabled for EIGRP

    network 10.1.0.0 255.255.0.0 ! only interface will 10.1.x.x will be
    enabled

    As above plus you can't assign 10.2.3.4 and 10.2.3.5 to different interfaces
    on the router with the same mask since they overlap.
    (unless they are like loopbacks with /32 masks)
