RE: OSPF Question...other devices in LAN cant intercept

Well, it is likely a game with wording if I had to guess. Yes, if you use
the proper form of OSPF authentication (MD5) other routers on the LAN will
not be able to READ the update information because it will be encrypted.
But, you have to very careful with wording here, because the other routers
will still RECEIVE the updates, since they are multicast by default. So,
you need to really make sure that you understand that intercept is not
necessarily equal to being able to read the data.
