I had a discussion with a co-worker about OSPF Network statements.
He is going to tweak some of our OSPF configs and one thing he wants to do is to remove the <mask> from the Network statements and use the interface instead.
Now I am asking him not to do that since it's much easier to read the CFG and see the entire Network that is advertized. With just an interface there is ambiguity. BTW, we are not using IPv6, only IPv4.
He says it's more efficient but I don't think so. I've seen large OSPF configs at AT&T and Qualcomm and they use the full Network, not an interface, for readability and possibly other reasons.
Is this just preference or is there a legitimate reason to use an Interface over the Net <mask>? This company I am with now does not follow many of the common standards and practices that I've seen at large companies and I see this as one of them.
Any help would be most appreciated.
