Hello, Sujata!
Would the result of the experiment differ if you set Message Age and Max Age 
to the correct values while leaving Hello Time and Forward Delay incorrect:
Message Age = 19 (encoded as 0x13 0x00)
Max Age = 20 (encoded as 0x14 0x00)
Hello Time = 255 (encoded as 0xFF 0x00)
Forward Delay = 255 (encoded as 0xFF 0x00)

How would Cisco switch handle such BPDUs?
