RFCs are not always strictly followed by vendors. If you ALWAYS follow the
RFC, you will sometimes have problems with getting something to work.
Sometimes Cisco chooses to make something work the exact opposite of the way
the RFC says it should work.
When it comes to making Cisco equipment work a certain way in the CCIE Lab,
I would go with Doyle over an RFC any day. So, in the unlikely event that I
ever take the exam, and am told to configure OSPF with only one area, area
1, I will not argue with the proctor about how that conflicts with the RFC.
I will know that it can be done, even if it is "bad form."
If I have a choice between reading 7000-10,000 pages of Doyle and other
well-written Cisco Press material and Cisco IOS docs and TAC articles, or
reading 7000-10,000 pages of RFCs and similar materials written by engineers
telling us the standard way that things are supposed to be, I will read the
Cisco material. Ideally, in a world with infinite time, one should read all
of both kinds of material. I am by no means suggesting that one should not
read the RFCs, but I am suggesting that one would be foolish in the Cisco
world to always "go by the RFC."
