IP Helper Address Command
Routers or Multilayer Switches cannot forward broadcasts, but enabling the IP Helper Address command allows it to forward UDP broadcasts and forward them as a unicast to the address specified. The command “ip helper-address” must be configured on the interface/VLAN receiving the broadcasts. On a MLS for all users in VLAN 10 then the IP Helper Address must be configured on the VLAN SVI.

ip helper-address 10.10.10.1
