    Is is possible to join two vlans using a juniper switch/router?


    vlan10 interface


    vlan20 interface


    bridged interface = vlan10 and vlan20 in the same segment


    I can't use the same vlan because my fiber device isolate all clientes if using the same vlan number. But I would to like to join two clients and my device works if I use two different vlan numbers.


    Basically the idea is traffic comming from vlan 10 needs go out through vlan 20 and traffic comming from vlan 20 needs go out through vlan 10.

    One way to do is to physically connect a port from vlan 10 into a port from vlan 20.
    But this doesnt scale because it requires two physical ports.
    Does the juniper allow to bridge two same subnet vlans using a virtual/pseudo interface?
