Hello again. I'm having some trouble understanding the "ip dhcp snooping information option" requirement.
>From my understanding, Option 82, may actually be a good thing (please correct me if I'm wrong) because it uniquely identifies the DHCP request. When the DHCP Relay Agent (switch) intercepts the DHCP Request, and Option 82 is enabled, it appends the circuit ID and remote ID (typically the switch's MAC Address) into the option 82 field and forwards the request to the DHCP server. With reference to Yusuf Lab 2 (Qn8.4) and other labs, when configuring DHCP Snooping, the forwarding of Option 82 information is disabled "no ip dhcp snooping information option" Why do we do this, when I thought that uniquely identifying the DHCP request is actually a good thing ? Or is it not ? I understand the requirement to disable it if the DHCP Server doesnt support Option 82, but I'm still confused about why else we should have it disabled. I need some clarification on this Thanks again Mark
