Xbee s2c router to router communication

So i have 3 xbee S2c modules. I have configured 1 xbee as coordinator and another 2 xbee as routers. How can i achieve data transmission between router 1 and router 2 or vice versa. I am working in robotic application where in real time my coordinator robot needs to get data from both routers and sometimes router 1 may need to get data from router 2 also.

For one to one communications, set the DL and DH of radio 1 to match the SL and SH of radio 2 and then the same thing for radio 2 to radio 1.

to send data to more than one node, use the broadcast address.
