1.I have two separe networks 192.168.0.0 and 192.168.1.0 ,they r physicall connected. What should i configure and where to configure so that host of each network can connect to other host in other network. 2.I have two separe Subnets(after subnetting a class B network),they r physicall connected. What should i configure and where to configure so that host of each network can connect to other host in other network

Thanks. We'll let you know when a new response is added.

You should not physically connect the two subnets together except via a router. Your router will require two ethernet ports, one connected to each physical subnet.

    If you have a layer3 switch you can setup vlans to do the routing or even a windows/linux box with 2 nics can do IP routing for you to establish connectivity between the two subnets or as stated above you can use a dedicated router to do the routing for you.

    I agree with the above responses. The networks should be separated by a router or by VLANS, this will also eliminate broadcasts between networks. Can you provide more details on how these networks are connected? Are they both sharing the same switch or are they separate switches connected via crossover??

    I also agree with the other comments, and I've done both. Having said that as I moved into having Gigabit clients on our network I found the routers to be a bottleneck. I work mostly in moving large amounts of data and have two networks for administrative reasons (one sub is DHCP the other static, we have about 100 nodes) Broadcast traffic not being too bad with that many hosts I supernetted them with a netmask. You also could do so just by setting the netmask to 255.255.0.0, then all hosts can see eachother. There would need to be only one gateway in this case though (two could work though not "clean") I actually use a more restricted supernet of 255.255.248.0 but it's worked out well. Not for everone though, lots of medium to low bandwidth hosts, grab an L3 switch or linux/win box to do the routing. Recommend >500MHz (bare min about 200Mhz) for 100Base and PCIe capable chipset for GigE and at least 1GHz.

    It really depends what you are trying to achieve, and why you have two subnets in the first place. You say the two subnets are physically connected but you don't say how. If the total number of nodes is not large and there is no strong reason to have seperate subnets then the supernetting suggestion would be the simplest solution. Otherwise to get sensible suggestions you need to give more information about your physical topology.
