problem with relay agent implementation

[Prashanth Penumarthy]

I have attached the files, for privacy policies am attaching only the screen
shot of the captures.
my_relay_disc_cap.png -------- capture of packets on my implementation
true_relay_disc_cap.png ---------- screen shot of the capture that works
correctly

thanks,

prashanth
