VLAN communication between Devices at different Geographical location .

[aminrizwansyed44816]

Wondering if anyone can advise , Is it possible to implement VLAN Communication between two sites in Geographical Location . 

If I want VLAN 10 at R1 side SW1 to only communicate with VLAN 10 at R4 side SW2

             VLAN 20 at R1 side SW1 to only communicate with VLAN 20 at R4 side SW2 . 

Attached is the rough diagram . 
Is it possible ? Do I need to add any configuration on R2 and R3 ?

Hi,

OTV or VXLAN allows such communication.

But the features might not available on routers which depending on model and firmware version.

Are you looking to extended the Layer 2 VLAN or Only VLAN IP (L3) communication.

you can do tunnel between R1 and R4 communicated with IP access.
