I've a single cisco router with 2 interfaces:
interface vlan 1: 10.152.0.126/25
interface vlan 2: 10.152.1.254/27
I've an IP phone sitting in vlan 2 subnet and it needs to get an I.P from DHCP server which is sitting in vlan 1 subnet. Now I do know that ip helper-address is required for phone to get I.P from another subnet; but just making sure which interface and which I.P do i specify in ip helpder-address command?
From my understanding, I think it should be on vlan 2 interface
Interface vlan 2
ip helper-address 10.152.0.126 ??? (I.P of vlan 1 interface) or
ip helper-address 10.152.0.102 (I.P of DHCP server itself) ???
