I´m sure this must be a very straighforward question, but what must I
consider when providing a DHCP server for servicing various subnets?
A "scope" for each such subnet.
Some way for the BROADCASTS by machines on the "other subnets" to
get them across the router(s) to the DHCP server:
1) Router as "BootP Forwarder"
OR
2) DHCP Relay Agent on subnet(s) without a DCHP server
Eg, building 1 uses address ranges 192.168.200.x, 201.x, 202.x according
to
the floor.
I presume I create 3 scopes
Yes
...and add them all as a superscope?
No, not unless you use all three subnets on the same "broadcast domain"
(i.e.,
without intervening routers). Superscopes are ONLY for multinets (multiple
subnets on the same broadcast domain.)
With three separate subnets on diffrent segmetns you just create three
scopes,
one for each subnet.
How does the
DHCP server recognise from which subnet came the DHCP request and know
from
which range to give the client their address?
When a BootP forwarder (router) or a DHCP Relay agent sends the DHCP
Discover
from client to DHCP server, it adds it's own IP address to the packet so
that when
the DHCP server receives it, the server will choose a scope that matches the
subnet of
the forwarder/relay device.
What do I need to conside in terms of routers?
BootP forwarding or DHCP Relay Agent.
