cc2530: what to do to pass Joined but not yet authenticated by trust center ?

hi

till now i have Zigbee device that is ZNP  and use as coordinator

and i have Zigbee device that i want use mcu 8051 in it as Router

in sample app, i add these lines as well as similar in znp to set up a coordinator

  bdb_setChannelAttribute(true,0x2000);
  bdb_setChannelAttribute(false,0x0000);

  bdb_initialize ();
  
  bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_STEERING);

in other zigbee that use znp i rcved this 

FEh 0Ch 45h CAh 6Fh 1Ch 94h 60h 6Bh 0Fh 00h 4Bh 12h 00h 00h 00h 39h

according to document 

and what my 8051 MCU return is this:

DEV_END_DEVICE_UNAUTH Joined but not yet authenticated by trust center

where should i authenticate ?how can i authenticate?

what is the function? 

should i authenticate in ZNP that is Coordinator or in 8051 that is router?
