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)
