hello all i want to connect intranet 8 branch of business office.which one is the best idea to used configure.
Depends on how you want them connected. Routed (IPSec) or Bridged (EoIP over PPTP).

http://www.mikrotik.com/documentation/manual_2.7/Interface/EoIP.html
I realize that documentation is for an older ROS release, but it details how to secure the tunnel with PPTP…something the Wiki entry does not provide.
not only 2 office branch i need to more than 2, at least 8 branch plz give the idea connected to 3 branches or which one is the best protocol also..
You can scale the IPSec implementation to more offices much easier than you can EoIP. I would recommend that approach.
