Hi,
The correct one is option 2
R6:
Ntp server BB1
Ntp peer R3
R3:
Ntp server BB3
Ntp peer R6
Ntp peer for BBx is not required

Ok, this was my point of view, however, the answer in iewbv4 lab 1 was
the second one(using ntp peer cmd) !
however, why are you adding the ntp peer BBx cmd?

Subject: Re: NTP: server vs. peer
peer is used to sync between master NTP
server is just to get the time
so you need
R6
ntp peer BB1
ntp server BB1 prefer
ntp server R3
R3
ntp peer BB3
ntp server BB3 prefer
ntp server R6

Hi all,
If I am asked to configure R6 to have its clock from BB1 then
failover
and get time from R3 if BB1 is down. Also, R3 get time from BB3
and fail
over to R6 in case BB3 is down.
What is correct:
1-
R6:
Ntp server BB1 prefer
Ntp server R3
R3:
Ntp server BB3 prefer
Ntp server R6
2-
R6:
Ntp server BB1
Ntp peer R3
R3:
Ntp server BB3
Ntp peer R6
Thanks for feedback
