How to setup a master and slave DNS?

Hello All,

I am still in the learning phase and all inputs are welcome

Domain is already registered and custom nameserver are already pointed.

example.com, ns1.example.com & ns2.example.com

I want to use ns1.example.com (Hurricane Electric, a third party DNS provider) as a slave DNS provider that will pull update from ns2.example.com as the master.

 

Thank you for the quick response but DNS Clustering isn't an option for me at this moment.

I am looking for a master/slave setup, whereas master is ns2.example.com (hosted locally) and slave is ns1.example.com (third party DNS provider, in my case Hurricane Electric).

I need help on how to proceed.

 

Thank you for all the replies.
