Are both lines of configuration necessary? I have seen OSPF examples of
clear-text and MD5 where just one line was configured on the actual
interface and the "ip ospf authentication message-digest" or "ip ospf
authentication" was ommited. I experemented with it an it seems to
function ok without the extra line. Is this line superfluous or is it a
legacy command?
