Intervlan routing

[chetan1405]

I have catalyst 1000 series switch. I have created 4 vlans. Vlan 100 192.168.100.1/24, vlan 160 192.162.160.1/24, vlan 161 192.162.161.1/24, and vlan 162 192.168.162.1/24.

In switch port 1-2 in vlan 160, port 3-4 in vlan 161, port 5-6 in vlan 162. I have connected 3 laptops, one in port 1 , and the other one is in port 3 and another one in in port 5. What configuration will require to communicate all three laptop to each other.

To enable the laptops to communicate you must enable ip routing.

Hello @chetan1405 

ip routing command need to be enable.

Hello,

in case the suggestion made by M02@rt37  and @Richard Burts  still does not make a difference, post the full running configuration of your C1000, as well as the output from 'ipconfig /all' from your laptops...

Make sure you create a Layer VLAN, Layer3 VLAN SVI (other suggested enable IP routing) - if all need to be in the same switch to connect each other,

If they need to contact externally, then you need  ip route to external path.

Others have addressed the configuration needs of the L3 switch, but don't overlook your laptop configs.  The laptop interfaces need to be have a correct VLAN subnet IP and gateway addresses, and depending on the hosts, they may have other requirements for intercommunication, such as host firewall rules.

Work on each switch interface and vlan at a time. Make sure your laptop IP config is setup correctly with correct gateway and ping the address on the switch.
With the IP routing enabled as above, then everything should connect.

If you believe your IP details are correct on the laptop and you still cannot ping the switch address. Then make sure you do not have any tagged, untagged issues. E.g. If you have access ports, then your laptop NIC should not have any tags. If you have created trunked ports and tagging, then your laptop NIC will need a vlan tag.

good luck

". . . ping the address on the switch."

BTW, from a laptop host, pinging its gateway IP is a good first test, but also try pinging other VLAN/subnet gateways, as that will require correct routing on the L3 switch.
