EIGRP Network Command

What is the correct way to use the network command in EIGRP? For example, if I use 10.0.0.0 in my AS, does that mean the correct command would be 'network 10.0.0.0' on every router? Or should I only use the network IP's of the directly attached networks on each router (eg 10.0.5.0, etc.)?

Hope that makes sense.

TIA.

Re: EIGRP Network Command

You can simply use 10.0.0.0 as the parameter for network command. This would enable EIGRP on those interface on the router, which are configured with an ip address from the 10.0.0.0 network (whether it be 10.0.5.0 or 10.x.x.x)

You can also use a wildcard mask after the command to narrow down the interfaces EIGRP will run on. So, for instance, if you have:

int s0/0: 10.1.1.1/24

int s0/1: 10.1.2.1/24

int s0/2: 10.1.65.1/24

network 10.1.1.1 0.0.0.0 would only run EIGRP on S0/0.

network 10.1.0.0 0.0.64.255 would only run EIGRP on S0/0 and S0/1.

network 10.1.0.0 0.0.255.255 would run EIGRP on all three interfaces.
