I have a router with multiple vlans that use the ip helper command. However, i need to define one particular vlan (for wireless option 43) for DHCP option 43. In the IOS of the router i can only define a global DHCP service. Here is my question - will the other vlans that request an IP address with they get the IP address defined on the global IOS defination or continue to use the IP helper IP address?
If an ip helper-address is configured on the interface which receives the DHCPDISCOVER packet, the packet will be converted to a unicast packet and sent to your DHCP server configured in the helper address.
If a packet is received on an interface not configured with a helper-address, the router DHCP will process it.
