padding before end of DHCPOFFER packet?

[Joseph Bernard]

Is it valid to have padding (0) before the end (255) of a DHCPOFFER packet?  I have a Cisco switch doing this, but I’m not sure if it valid.  I have some old HP Jetdirect boxes that will not take a packet constructed like this.  I just want to be sure if the padding is valid or not so I don’t mistakingly accuse Cisco of having bad code.


Thanks,
