Requirement:

Customer has Layer 2 switch and 3 VLAN's are created. Customer wants inter-vlan communication. 

Hosts in different VLANs cannot directly communicate with each other. We need to configure Layer 3 routing to allow all VLANs to communicate.  Routing is not possible on Layer 2 switch .

We need to configure Inter-vlan  routing on the router.
We have to create sub interfaces and need to encapsulate with 802.1Q protocol so the Interface can understand the VLAN traffic.

• Create Sub interface 

                    interface interface-type interface-number.subnumber

• Configure 802.1Q encapsulation 

                   vlan-type dot1q vid <vlan-number> 

• Assign IP address 

                 ip address X.X.X.X X.X.X.X

Router Configuration  : 

Switch Configuration  : 

VLANs & UP-Link

End Users Interfaces
