DAI conflict with inter-VLAN routing

[raoufesi]

Hey community, 

I have a 3-tier architecture, with 4 VLANs 10-40, I configured inter-VLAN routing on distribution switches and it's working fine, however when I pursued to configure DAI on access and distribution switches inter-VLAN routing is not working anymore, I configured the interfaces connected to switches as trusted and left those connected to end hosts on their untrusted default state, can someone help me with this issue ?

DHCP was not correctly configured...

Partly yes, the main issue is the DHCP server that wasn't configured just yet, so I configured it as well as the per-vlan ip dhcp snooping as you mentioned and the problem is solved, thank you sir...
