 ] Not a whole lot, since you cannot rely upon hearing every version of
 ] every LSA, only the latest one.  There are a number of scenarios
 ] in which an LSA being flooded can be overtaken by a newer version,
 ] and thus the older one may not be delivered to everyone.

If router X received LSAs from router A with version a, b, c and d;
router Y only received a and d. If both X and Y decide to do version/
content comparison, it just means X is going to do 3 times, and Y
is going to do one time only. But the end result should be the same
since they all get the finally version of d. Unless the version/
content comparison code has problem.
