As per my interpretation: -
"R1 does not need to authenticate R2 when calling" -
- requirement is asking for 1-way authentication
- R1 is the calling party (initiating)
- R2 is the called party (receiving)
- R2 will authenticate R1, however R1 will not. (ppp authentication chap callin)
Look out for key words like "secure" or "3-way handshake" for CHAP. PAP is considered unsecure and uses 2-way handshaking.
Question: If nothing is mentioned about authentication &/ security, should we: -
1. Don't configure any PPP authentication at all, OR
2. Use either CHAP or PAP ???
"Callout" - use on a local router context, means the router will initiate the call.
"Callback" is quite simple to spot if one understands what callback is about.
Normally, part 2 of the ISDN section deals with DDR. From there, you will have a better idea of who should call who and when. So it is important to read and understand both parts of this section before you begin your configuration.

Does anyone have a good way to know which type of
authentication is required depending on what is asked?
What I mean is, I am having a heack of a time trying
to distinguish between (callin, callout, callback)
authentications.
Things like R1 does not need to Authenticate R2 when
calling. (callin, callout?)
Thanks,
