Re: OSPF Authentication Methods - (3)

I always saw it as a two step process as well, you enable authentication and
then, apply. When you enable authentication it needs to be enabled on both
ends of the link. So i guess we are saying the same thing.

But i still have problems with OSPF having three authentication methods.
Especially when they say type "0" is one type of authentication and when you
look it up, it states that "0" means NO Authentication.

But i see everyones point here.
