We have several different VLANs running on the same Catalyst 4500 switch. Our DHCP/DNS servers reside on one of these VLANs, and client PCs reside on a different VLAN. If we point our client PCs to the DHCP/DNS servers on the other VLAN, do we have to use the IP helper-address command so that the DHCP/DNS broadcasts will be forwarded to the appropriate VLAN? Even if both VLANs have SVIs (i.e. are directly connected) on the same switch?
I'm thinking that we'll still need the IP helper-address, because a VLAN is a broadcast domain and the switch, by default, won't forward broadcasts between broadcast domains.
