A company has a centralized DHCP server at 10.50.1.10 located in the data center. Client PCs on VLAN 20 (subnet 192.168.20.0/24) connect to a Layer 3 switch that acts as their default gateway on interface SVI Vlan20. Users on VLAN 20 report they cannot obtain IP addresses automatically, while statically configured hosts work fine. What configuration must be applied to the Layer 3 switch to resolve this?
