I'm a first year network engineering student and just got into Cisco today, so please bear with me..

I'm trying to setup two switches to connect to each other via a router

. like this

but I can't seem to make devices from the A switch to connect to devices from the B switch. I tried searchinig on Youtube and found one that works but it uses a DHCP server to assign IPs to the connected devices like this..

. dhcp

Is there a way to connect devices from the A switch to B switch via a router without DHCP server ? If yes, can you help me configure it? I have uploaded the .pkt file if needed

  • it's not actually a homework i was just trying new things to get ahead for the next material.. but sure – Andi Reyhan Apr 20 '16 at 18:26

You don't need DHCP to make them talk to each other.

First make sure you can ping the default gateway (it's the LAN facing interface of the router Fa0/0 and Fa0/1).

Check the IP addressing. The router has two directly attached networks. To make it work only proper IP addressing is required. Did you configure VLAN's ?

  • It worked ! I was entering the interface's IPs as dns server on the nodes and left the gateway empty.. after filling the gateway with the interface ip it worked wonderfully, thanks ! – Andi Reyhan Apr 20 '16 at 10:30
  • can you explain the difference between the two? teacher told us to use interface IP as dns server on the end devices but that didnt work – Andi Reyhan Apr 20 '16 at 10:32

Just configure static IPs on your terminals, with good netmasks / subnets, and then:

  • for the switch A sub-network, give Router0.Fa0/0 adress as default gateway;
  • and for the switch B sub-network, give Router0.Fa0/1 adress ad default gateway.

And then, on your router, add the two sub-netorks on your routing table.

    There's no need to edit the routing table. Both networks are directly reachable. The router has all it needs to route between both networks (assuming he configured the addressing properly). – cyzczy Apr 20 '16 at 10:19
