NTP question for group of servers

[MQ'ski]

Hello.
I have following question.
I have four nodes :
node1 node2 node3 node4
The idea is that node4 has primary and secondary NTP server from external source.
node3 has the same configuration.
node1 and node 2 should be synchronised to node4 if alive or if node4 is down to node3.
So I configured as follows:
node1 and node2
have in configuration as follows:
primary node3
secondary node4

node 3 and node4
primary externalsource1
secondary externalsource2

The question is. If all servers should be configured correctly to keep proper exact time...
Should node3 and node4 have in config as peer each other?
Thanks you!

Shalom,

It would not hurt to have node3/4 which have outside access to be peers. It is not required.

If all servers are configured correctly and you manually adjust to make sure they are within a few hours of each other, they will sync up in a few hours and keep excellent time even if the Internet is unavailable to node3/4 for some time.

I should add...
All of the servers are in the same network.
and configured correctly I think...
So I assume from you answer it is enaugh what I have done.
Thanks!
