[ntp:questions] NTP not syncing to configured servers

Hi,

I am seeing ntp not syncing to external configured servers. We tried both 4.2.4 and 4.2.6 versions.
The following is the configuration,

We use two servers 10.126.142.198 and 10.126.142.204 in our Lab.
They are statically configured as running @ stratum level 5 and providing the clock from its own local clock.

Even though the servers does not have a valid reference time and provides time from its own clock,
according to me still we need to be able to sync to it since it is running at better stratum.
Please clarify.
