Xbee Broadcast With arduino mega

hi,
I have a little question:
I am working with xbees. configuring xbee to the broadcast port solves the problem earlier. However, now i am using arduino mega and there is embedded xbee shield . How can i configure the xbee shield to the broadcast mode in arduino mega.

Thanks.

How can i configure the xbee shield to the broadcast mode in arduino mega.

The XBee shield has nothing to do with whether the XBee is in broadcast mode, or not.
