[baba_yaga]

I didnt get ip address for my Client PC & the error message is "dhcp failed apipa being used" I try to make DHCP server on Router, DHCP Relay on Multilayer Switch & Vlan on Switch.

This is the topologyDHCP, DHCP Relay & InterVlan

What I missed for configuration, thanks

I found some misconfigurations on devices as:

Router:

a. Remove the subinterface (Gig0/0.10) for VLAN 10 because L3 routing is configured on Multilayer switch. 

   Run the following command

   "no interface gig0/0.10" 

B. Add a route toward to inside network (VLAN 10)

   Run the following command

    "IP route 192.168.1.0 255.255.255.0 10.10.10.2"

Switch

a. Make trunk to interface GigabitEthernet0/2

   Run the following command

   "Switchport  encapsulation dot1q"

   "Switchport mode trunk"

Don't forget to vote, If your query will be resolved.

Thanks,

Thanks man it works, Ok correct me if I wrong.
So in router do not add subinterface (Gig0/0.10) again for VLAN?
Must Add a route toward to inside network (VLAN 10) and use "IP route 192.168.1.0 255.255.255.0 10.10.10.2" like that or can I add any route dynamic?
And if I don't use Router just Multilayer switc(as DHCP server too) directly connect to switch must add too ip route?
