how to do intervlan routing between two hosts in different subnet separated by two layer 3 switches & without using ip routing command & by using the concept of native vlan.

Since there is no common layer 2 connection between distinct VLANs they need to communicate through a layer 3 device - a router. If you don't want your L3 switches to route you require an additional router.

The native VLAN (of a trunk port) is the VLAN untagged traffic is associated with. This is unrelated to routing.

Edit: for a more specific answer you'll need to provide a more specific question: provide a network diagram, switch models, switch configurations and I'll update the answer.

  • i was asked this question by my mentor & she told me there Is a way to do that & she gave me a hint to use the concept of native vlan. – Harshil Mahanoori Apr 4 '18 at 6:39
  • i have taken host a with ip address 192.168.10.1 which is connected to l3 switch wit fa0/1 interface & is in vlan 10 , the layer 3 switch is connected to another layer 3 switch wit interface fa0/2 & fa0/2 repectively & both its interfaces are in vlan 30 & are using ip address 10.1.1.1 & 10.1.1.2 respectively.the layer 3 switch is connected to host b with interface fa0/1 & is in vlan 20 with ip address 192.168.20.1 & i am providing static routes on both the switches. so is there a way to achieve this configuration but without using static routes. – Harshil Mahanoori Apr 4 '18 at 6:44

    You do need a router. You can point each node's default gateway to this router or use static routes. I still don't see the relation between inter-VLAN communication and native VLANs. PS: please add specific details to your question - nobody is going to read all the comments to figure out what you're asking. – Zac67 Apr 4 '18 at 10:59
