How to glue a site in the ru zone correctly with a domain in the rf zone?

Question

CMS

Who will tell you what it is eaten with!
There is a news blog on the Internet - in the ru zone . WordPress engine!
Today I bought the same domain, only in the Russian zone and decided to make a copy of the site on the Internet.
Example:
Main domain:
slon.ru
slon.rf It is
necessary to make two sites work on the Internet with the same content. It will be in the ru zone as the main site . That is, all work with the blog will be carried out on the main domain name ru , as well as that the information is updated on the second domain name in the rf zone .
I would be very grateful if anyone could share the info!

Then there will be a big problem, since Wordpress stores links directly with the domain
