Hi @gcngov , this does not appear to be a GNS3 related issue. Your R1 router is missing a DHCP pool and even the sub-interface for VLAN10.

In the future, please post similar issues in appropriate threads on the GNS3.com forum. Many more will be able to help you find your problem there.

For now, just run the below commands on your router R1 and your VPC client should then receive IP address. It should also be able to ping the L3 switch (10.20.222.2) and R1 (10.20.222.1).

R1:

R1(config)#ip dhcp pool POOL10
R1(dhcp-config)#network 10.20.222.0 255.255.255.0
R1(dhcp-config)#default-router 10.20.222.1
R1(dhcp-config)#exit
R1(config)#int f0/0
R1(config-if)#no shut
R1(config)#int f0/0.10
R1(config-subif)#encapsulation dot1Q 10
R1(config-subif)#ip address 10.20.222.1 255.255.255.0
R1(config-subif)#end

If you are certain your configuration is correct, please post packet captures from both the links. You can use "bootp" filter in Wireshark to see only DHCP traffic.

@sairuscz Thanks for helping resolve this.
@gcngov Can you check that?
