How to connect these networks?

How to connect these networks ?? Cheap and best solution ?? Kindly Help?


1st network having IP in series (16 computers)- This is my branch office


IP 10.1.241.xxx


subnet as 255.255.248.0


Wired and having static IP


Interconnected through Ethernet wire and unmanaged switches


PC--%26gt; switch--%26gt;PC--%26gt;switch --%26gt;PC--%26gt;switch--%26gt;PC .........











IInd network having IP in series (19 computers) - This is my office


IP 192.168.0.XXX


Subnet mask 255.255.255.0


wired and having static IP


Wired and having static IP


Interconnected through Ethernet wire and unmanaged switches


PC--%26gt; switch--%26gt;PC--%26gt;switch --%26gt;PC--%26gt;switch--%26gt;PC .........








These two networks are nearby and about 15 mtrs apart (opposite buildings) and no servers are there. i want to connect all these PC together. so that they are accessible to each other.








Is there any way to connect above two networks so that we may access all the computers existing on both the networks. Shall we require a router for that.





Or it may be achieved by putting IPs in DNS server address preffered IP and alternate server address IP ie. starting IP our network in preferred and other networks starting IP as alternate.





i did try to connect the networks with a Ethernet wire through the vacant ports of existing switches and changing DNS settings but was unsuccessful.





Kindly assist please.|||My understanding of this is that the easiest way to do this is to have both networks in the same IP block. Set router1 in building 1 to 10.1.1.1 for example and have the DNS turned on.


Then put a switch or turn off DNS in router2 in building 2. Run an ethernet wire from one of the LAN ports on router1 to the WAN port in the switch or router2. Router1 will reassign IP addresses to all units in both groups. You will have to turn off all computers and restart them one at a time.





Another choice is to set router2 at 10.1.250.1 and turn its DNS on. Still run the ethernet wire from a LAN router1 port to the WAN port in router2. This will assign numbers 10.1.1.2 up (you can limit this to perhaps 100 computers) for the building 1. This will assign 10.1.250.2 up to computers in building 2.|||I will recommend you purchase two routers. Two Cisco 2600 routers (as an example only) could be configured to accomplish your task. Without routers your two networks can not communicate with each other.


Altering the DNS will not help either in that scenario.





Example: Router 1 Location 1


You set up a network. 10.1.241.x subnet 255.255.248.0 (10.1.241.x/21)


You would configure R1 to that network but then you would also add another network to connect the two routers together - 10.1.1.1 255.255.255.0





Now - 10.1.1.1 255.255.255.0 is going to connect to router two like such: 10.1.1.2 255.255.255.0 (notice host on first router is 1 and 2nd router is 2 )





You would repeat the process on the second router but you would use (obviously) the IP%26#039;s that pertain to that routers network.


NOT EXACT but here is an idea on Cisco router:


I%26#039;m using different IP scheme too.





R1#: interface fa0/0


ip addr 192.168.1.1 255.255.248.0


router rip


network 192.168.1.1


network 10.1.0.0


no shutdown





R2# interface fa0/0


ip addr 192.168.2.1 255.255.255.0


router rip


network 10.1.0.0








again, I left out a LOT of commands but this was simply just to give you an idea
