What's the relationship between option 82 and DHCP snooping?
You can choose not to insert option 82. But why won't you?
On the access switches it's required to configure:
ip dhcp snooping
ip dhcp snooping vlan x y
and on trunks:
ip dhcp snooping trust
but do you have to configure something on the distribution layer or on a aggregation switch?
What if an access switch is not configured for DHCP snooping in a 'DHCP snooping configured' network? Will these clients able to receive an IP; will the switch understand option 82.
Thanks in advance
