hello,everyone,i want to set an agent's address and port ,so i use

        #$tcp0 set agent_port_ 888
    #$tcp0 set dst_port_ 999
    #$tcp0 set dst_addr_ 3

        $sink0 set agent_port 999
    $sink0 set agent_addr 3

        $ns connect $tcp0 $sink0  
but after simulating, i find in the .tr file ,the dst's port and addr  is still 
"3.0",
and not the 3.999,and in the c++ file,i still see the same result of the 
packets in the queue
,so if want to change the dst_port_ and dst_addr of a packet in the init 
stage,how need i do?
