My company has a cisco 2621 router with one s0 and 2 Fast Ethernet ports.
here is the scenario, one side of the network is 10.0.0.0 with subnet mask at 255.255.255.0 running an NT 4.0 server /with dhcp running and use 2 24 port hubs. On the other side, I have a network of 10.1.0.0. With a windows 2000 member server running DHCP for the 10.1.0.0. So both networks have DHCP running. 1st I want to know how to configure the router to route both networks with out having Dhcp forwarding to each others network. 2nd, once the router is configured and Eth port 2 (10.0.0.0 )is working, do I run eth port 2 cable from the router to The hubs on 10.0.0.0 or do I have to have another router put into the 10.0.0.0 network and will it route to a gateway of 10.1.0.1 which is my internet gatway so both but different networks can use the internet on gateway 10.1.0.1.
DHCP requests will not be forwarded between networks, unless a ip-helper command is on the interface the DHCP requests are occuring.
I'm not clear on exactly what you're explaining routing wise, but will try to answer the question. It sounds like one ethernet has a 10.0.0.x/24 network and the other ethernet interface has a 10.1.0.x/24 network. Am I correct? If so, then both networks are directly connected on the router so a routing protocol is not really needed unless the internet gateway is using a routing protocol. On the internet gateway, you would have a static route for 10.0.0.0 with mask of 255.0.0.0 pointing back to the 10.1.0.x address on the 2621. This may not be the case if I didn't understand your question correctly.
Basically all i want to do is network the two network with the 2621 router and share the internet connection (the gateway address is 10.1.0.1) Both servers on each network is running DHCP I do not want the broadcast from the DHCP servers to give addresses out on the opposite network. I have the ehternet cable from the ethernet port 1coming from the 2621 and it feeds the 10.1.0.0 255.255.255.0 network This works fine. This is the problem I am having. on the 2nd ethernet port. I want to add 10.0.0.0 255.255.255.0 network to the routers 2nd ehternet port and use the internet gateway (10.1.0.1)for both networks. I do not understand the static route clearly. Please give example.
DHCP will not be forwarded unless you specifically enable it. Since you don't want this (based on your first post) you don't need to worry about it.
As for your problem, the 10.0.0.0 255.255.255.0 can't have the same gateway as 10.1.0.0 255.255.255.0, they are on different subnets. Your second ethernet port clients need a gateway of 10.0.0.x. Make their gateway the second ethernet's IP.
Your first ethernet port clients can keep 10.1.0.1 (first ethernets IP I assume) .
