I've tried to dig on Cisco.com website about this but all information leads to "ip forward-protocol udp" which helps the dhcp process (in-short). While I'm actually looking the proper explanation for "ip forward-protocol nd" I only got that parameter "nd" is used for old SUN network disk which I have no idea whether that still in use in current civilization. What is this command for and what is exactly Sun network disk?
Did anyone ever answer you? I see you posted also at a Cisco forum and got a response that didn't really answer the question. ;o) I was looking for the same answer, what is ip protocol-forward nd, and find only you...
