Virtual Routers
ExtremeWare XOS 11.3 Concepts Guide

Using Virtual Routers—BlackDiamond 10K Switch Only
To use the user virtual router functionality in ExtremeWare XOS, you will need to do the following
things:
●
Create the virtual router
●
Configure ports to a single virtual router, or to multiple virtual routers
●
Add any required routing protocols to the virtual router
●
Configure the routing protocols and VLANs
The following sections describe how to do these tasks.
Creating Virtual Routers
To create a user virtual router, issue the following command:
create virtual-router <vr-name>
A virtual router name cannot be the same as a VLAN name. You cannot name a user virtual router with
the names VR-Mgmt, VR-Control, or VR-Default because these are the existing default system virtual
routers. For backward compatibility, user virtual routers also cannot be named VR-0, VR-1 or VR-2,
because these three names are the names for the system virtual routers in ExtremeWare XOS releases
prior to 11.0.
To delete a user virtual router, issue the following command:
delete virtual-router <vr-name>
Before you delete a virtual router, you must delete all VLANs created in that virtual router. All of the
ports assigned to this virtual router will be deleted and made available to assign to other virtual routers.
Any routing protocol that is running on the virtual router will be shut down and deleted gracefully.
Configuring Ports to a Single or to Multiple Virtual Router(s)
By default, all the user data ports belong to the system default virtual router, VR-Default, and belong to
the default VLAN, Default. All these ports are used exclusively by the virtual router, VR-Default. To
configure a port for exclusive use by another virtual router, or for use by multiple virtual routers, it
must first be deleted from VR-Default. You must delete the port from any VLAN it belongs to before
deleting it from a virtual router.
To delete a port from a virtual router, issue the following command:
configure vr <vr-name> delete ports <portlist>
Adding Ports to a Single Virtual Router
When you add a port to a virtual router, that port can only be used by that virtual router.
To add a port to a single virtual router, use the following command:
configure vr <vr-name> add ports <portlist>
