It depends on the requirements.
I reiterate: The 'ppp authentication' commands instruct the router as to
where and when to challenge the REMOTE end.
Placing 'ppp authentication chap callin' on r2 will still force r1 to
authenticate if r1 calls r2. If r2 calls r1 then r1 will not have to
authenticate.
Not configuring ppp authentication at all on r2 will never force r1 to
authenticate no matter who calls whom.

OS you are saying R2 should be configured with ppp authentication chap
callin,
Or are you saying do not configure ppp authtiencation on r2 at all.???

The 'ppp authentication' commands instruct the router as to where and when
to challenge the REMOTE end. If a router is challenged, it has no choice but
to attempt to authenticate. So in your scenario, it's not up to r1 (not
configurable on r1). It's up to r2. r2 must be instructed not to challenge
(authenticate) r1.
With this in mind, 'ppp authentication chap callin' configured in r1
instucts r1 to challenge the calling party when r1 is the called party (r2
calls r1). Whether or not r1 itself is challenged during this call depends
on how r2 is configured. In the same scenario, if r1 were to call r2, r1
would not challenge r2 ("r2 would not have to authenticate") because its a
"callout" from r1's perspective. Whether r1 is challenged during this
callout still depends on how r2 is configured.

I have seen this question asked before, but I am still not sure, If scenario
asks, " r1 should not authenticate", only r2 should authenticate.
I am thinking I have to setup ppp authenticate chap callin on r1,
Is this correct?
