I currently have two different devices (one server and one client device) that are on separate VLANs (VLAN 5 and VLAN 10 respectively). When the client device runs a tracert to the server, the tracert is able to complete as such.


Tracing route to []
over a maximum of 30 hops:

 1     6 ms   <1 ms   <1ms
 2    <1 ms   <1 ms   <1ms []

Trace complete.


My understanding is that a layer 3 router is required to route traffic between VLANs, which we have connected to the layer 3 switch. Is this correct? Why am I not able to see the Layer 3 router's IP within the tracert output?

Yes. Layer 3 device is required. It could be Layer 3 Switch as well. No separate router is required. According to your explanation Intervlan routing has been configured. If you have Layer 3 switch, SVI is required to communicate between vlans. According to your Explanation will be SVI(Switch Virtual Interface) or Gateway of your current VLAN.


You are. The first line is the interface of the router.

  • Sorry, I did not clarify. is the IP address of the interface VLAN that the client is sitting on.

    Yes, the vlan interface is the layer 3 switch which does the routing.

Actually information provided is not clear not not enough to provide your the answer . Still clarification to your questions with possible examples scenario..

Example 1

If VLAN 5 and VLAN 10 are configured in router inter -VLAN routing than traffic will reach router interfàce to pass the traffic between different subnets or different VLANS .

Traceroute output will be

1 ) Client default gateway ip (VLAN 5)

2 ) VLAN 10 gateway ip address

3 ) Actually server ip address .

Traffic flow scenario will be same if SVI are configured in layer3 switch instead of in router
