DHCP Snooping and ip helper
Hi group,
I am looking for details regarding DHCP snooping when implemented on the standard 3-tier design:
[L3 switch - ip and HSRP defined for vlan x] —————– [L2 Access switch with ip for management in vlan x]
The L2 access switch is running DHCP snooping. Wheir do i have to configure my ip helper address ? On the L3 switch or on the L2 switch ? I have the impression that my DHCP is not working anymore if i enable ip helper on L3 switch and DHCP snooping on the L2 switch… It only works when ip helper is defined on the L2 switch. Why ?
Does anyone have details regarding the interaction of ip helper address and DHCP snooping ?
regards, Geert
