[OSL | CCIE_RS] Network command

[Roger]

Hi Group,

I have a general question regarding the mask of the network command within
the routing protocol. Let’s say you have configured and interface with the
address 172.16.1.1/24 and you want to have it in your OSPF. Which mask –
wildcard do you configure?

network 172.16.1.1 0.0.0.0 area xy

or

network 172.16.1.1 0.0.0.255 area xy

Sure, I understand the difference, with the second example I have the whole
class c in OSPF, but does it really matter? How is it in the LAB?
>From my praxis work, I would use always the second example...

Thanks

Roger
