Joining Two Large Network Research
I have a church I'm trying to help out with a network topology.
Theyhave a school and a rectory they want to connect via fiber.
However, the school wants to continue with their outbound internet
connection and DHCP server. The rectory also wants to continue
withtheir outbound internet connection and DHCP server.
Consolidation is NOT a possibility.
My thoughts are to use existing Dell PowerConnect 5324 switches.
Ithas an IOS-esque interface and has a lot of power that I've never
explored.
My plan would be either:
Plan A:
Give the switch two vlans with an IP address appropriate for each
side. Add a route from the existing routers on each side to
theswitch IP.
In my head, this seems like it might theoretically work but there
isthe question: can the Dell 5324 route packets between vlans?
Plan B:
Give the switch two vlans with two ports in common. On the port
incommon, block broadcast packets to block the DHCP.
Before someone suggest Plan C, the physical wires are spread out
accross a multi-acre facility. Handling access via wire control to a
specific port is simply impossible. Switching to static IPs
andremoving DHCP is also simply not maintainable/realistic.
Anyway, after that it gets worse because they want the lans tied
together but only for a few machines to cross over between them. I've
researched that part and I can do MAC address filtering and
theyunderstand that MAC's can be spoofed.
Any thoughts?
Thanks ahead of time.
I don't know if the PowerConnect 5324 supports Layer 3 routing, but
if it does then you should be fine. If not, you could always throw
in a Windows box with a couple of NICs and an appropriately configured
routing table. (Or, if you are so inclined, you could do the same
thing with a certain unnamed open source operating system--but we're
not allowed to discuss those sorts of things in this NG.)

Scott
