Dear all,
I need some help please..
I am not an experienced networking engineer..
I want to deploy zero touch provisioning in a Service Provider network. End-switch is located within a Ring. Each Ring is assigned a separate mgmnt_vlan. Ring is connected to a router with sub-interface.
interface GigabitEthernet0/0/1.<mgmnt_vlan>
ip address 172.16.1.0 255.255.255.0
ip helper-address 172.16.203.2
i am using isc-dhcp-server as dhcp server at 182.16.203.2.
My question is : if i provision the helper-ip as shown above, will the end-switch deploy the dhcp ip in
interface <mgmnt_vlan>
or will it be in
interface vlan 1 ?
Sorry, i couldn't arrange a setup currently to test this, so i am asking.
I tested following scenairo :
end-switch is connected through a layer3-device : on layer3-device, config is as follows :
interface Vlan670
ip address 172.16.31.1 255.255.255.0
ip helper-address 192.168.203.2
and in this case, end-switch deployed dhcp ip in vlan 1
interface Vlan1
ip address dhcp
just in case, my isc-dhcp-server / dhcpd.conf is like this :
subnet 172.16.31.0 netmask 255.255.255.0 {
range 172.16.31.161 172.16.31.165;
option subnet-mask 255.255.255.0;
option routers 172.16.31.1;
Thanks in advance ..
