InterVALN Routing in Switch 3850

InterVALN Routing in Switch 3850

InterVALN Routing in Switch 3850

I am trying to establish the link between the computer form different VLANS on separate switches. Computers are pinging to each other form different VLAN within the switch. But not able to communicate other VLAN on different switch. My scenario is as follows.

No Router in the environment. Trying to make it work through switches.

Switch 1 (Layer 3 Switch)

I created first VALN with ID 116 and assigned IP
Assigned port fa0/1.
PC1 is connected to fa0/1 and assigned to VLAN 116. IP of computer (Gateway

I created second VLAN with ID 131, IP
Assigned port fa0/2.
PC2 is connected to fa0/2 and assigned to VLAN 131. IP of computer (Gateway

Switch 2 (Layer 3 Switch)

I created third VALN with ID 132 and assigned IP
Assigned port fa0/1.
PC3 is connected to fa0/1 and assigned to VLAN 132. IP of computer (Gateway

I created fourth VALN with ID 230 and assigned IP
Assigned port fa0/2.
PC4 is connected to fa0/1 and assigned to VLAN 230. IP of computer (Gateway


PC1 and PC2 communicating each other and it is the same in case PC3 & PC 4

Now I want to make communication between the VLANS of both the switches. I tried using RIPv2 but didn't work. I also assigned ip to g0/1 on switch 1 and to g0/1 on switch 2 but this method also didn't work.

Could anybody help me in what type of command I am missing to make communication.

Did to you tried enabling trunk?
Mainly it is used to carry trffic between switch

RE: InterVALN Routing in Switch 3850

Yes. I tried trunking too by the following commands

switchport trunk encapsulation dot1q
switchport mode trunk

But didn't work out. Trunking is Layer 2 capability ?

RE: InterVALN Routing in Switch 3850

For the future, switch configurations would be helpful. Having said that, I am assuming:
All subnets that you associated with VLANs are /24 (mask is and I assume and belong to the same subnet as well.

Sw1 connection to Sw2:
on each port add:

CODE -->

no switchport access 
On sw1:

CODE -->

ip route
ip route 
On Sw2:

CODE -->

ip route
ip route 

RE: InterVALN Routing in Switch 3850

Thanks for an update but I stacked the switches and able to create all the vlan in one entity and IP Routing did it's magic. But my next question is can I create same VLANs (IP and ID) on 3750-X switch and connect them through making two ports as Etherchannel on both the switches by assigning the IP and make Static Routes.

I need some more ports for the existing VLANs in Stack 3850 that is why I am planning to attach 3750-X to it.
