This should be perfectly acceptable, remember that all the network command does
is match IP addresses and tag the interface as participating in the routing
process. However in some cases where you are cutting and pasting it may be
easier to use the network command differently.
Example would be configuring OSPF or EIGRP on multiple routers for the same
network.
10.10.10.1/24
10.10.10.2/24
10.10.10.3/24
10.10.10.4/24
In this case it's much easier just to use the following and then copy/paste to
all routers
router eigrp 1
no auto-summary
passive default
network 10.10.10.0 0.0.0.255
Ultimately you will do what works for you, but the more time you can save the
better!!! :)
Good luck and when is you lab?

Subject: [OSL | CCIE_RS] Wildcard mask with EIGRP
I use a wildcard mask matching the exact interface that I want to advertise in
EIGRP the very same as in OSPF
I have never had any issues but I want to make sure of it before LAB day.
Example
inter fas 0/1
ip address 10.10.10.1 255.255.255.0
inter serial 0/1
ip address 20.20.20.1 255.255.255.128
If I used OSPF
router ospf 1
network 10.10.10.1 0.0.0.0 area 0
network 20.20.20.1 0.0.0.0 area 0
If I used EIGRP
router eigrp 15 (this is my preferred method)
network 10.10.10.1 0.0.0.0
network 20.20.20.1 0.0.0.0
or
router eigrp 15
network 10.10.10.1 0.0.0.255
network 20.20.20.1 0.0.0.127
