Is it possible to create subinterfaces in different VRs on X670 going to the same trunk port?

I have read on this board:
Extreme doesn't use sub interfaces. The closest equivalent would be adding the port to the vlan tagged.

Ok, Juniper firewall with subinterfaces, e.g. ge-0/0/1.3 and ge-0/0/1.110, going via trunk to port 1 on an eXtreme X670.

I would like to assign VLAN 3 to a virtual router, and VLAN 110 to another virtual router on the X670.

Port 1 of the X670 can only be assgined to one virtual router. Is it possible to use subinterfaces on X670, that one sub-interface with VLAN 3 ends in one vr, and VLAN 110 ends in another vr?

I know how to do this on Juniper switches via irb (integrated routing bridging). Does somthing similar exist for eXtreme?

Hi Frank, Hi Stefan! Thanks for your feedback. That actually solved my issue. Much appreciated!

Nearly correct. 🙂 You need to leave out the “VR”, so it’s “configure VR-Default delete ports 44”.

You would have to disassociate the port from the VR first.

I’m not sure about the syntax, probably something along the lines of “configure VR VR-Default delete port 44”

* X670-48x.1 # create VR-Foo
* X670-48x.2 # create vr VR-Foo
* X670-48x.3 # create vr VR-Bar
* X670-48x.4 # create vlan ACME vr "VR-Foo"
* X670-48x.5 # create vlan CORP vr "VR-Bar"
* X670-48x.6 # configure vlan "ACME" tag 555
* X670-48x.7 # configure vlan "CORP" tag 666
* X670-48x.8 # configure vlan ACME add ports 44 tagged
Error: Port 44 belongs to virtual router VR-Default. VLAN is created on virtual-router VR-Foo

Someone correct me if I’m wrong, but if you don’t assign an interface/port to a VR, then you can assign the VLANs to whatever VR you want.

If you have two VRs, VR-Foo and VR-Bar:

create vlan "ACME" vr VR-Foo
create vlan “CORP” vr VR-Bar

Then you should be able to say:

configure vlan ACME add port 44 tagged
configure vlan CORP add port 44 tagged

I don’t have ports assigned to VRs on my switches, so I don’t know what the possibilities/restrictions are once you do that.

Hope that helped!
