question regarding proxy for dhcp..........
let's say you have a router R1 attached to subnet 10.1.1.0 and you want R1
to provide user on that subnet with dhcp addresses but the dhcp server is
located on a different subnet with address 10.2.2.2 would you configure R1
as follows?
ip helper address 10.2.2.2
No ip dhcp conflict logging
ip dhcp-server 10.2.2.2
ip dhcp excluded 10.1.1.0 10.1.1.100
ip dhcp pool 1
default-router 10.1.1.1
domain-name cisco.com
network 10.1.1.0
or would you just use the ip helper-address 10.2.2.2 ? or do both ways
work? i'm a bit confused as to how (and why) the 1st would work, although i
believe i've seen it done. in ex. 1 it seems to met that R1 IS the dhcp
server so i'm not sure why you would need a second dhcp server to provide
the addresses when R1 is providing them.
TIA
