●
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.
Adding Ports to a Virtual Router
By default, all the user data ports belong to the system default virtual router, VR-Default, and belong to
the default VLAN, Default. A port cannot belong to more than one virtual router, so before you add a
port you may need to delete it from another virtual router. You must delete the port from any VLAN it
belongs to before deleting it from a virtual router.
To add a port to a virtual router, use the following command:
configure vr <vr-name> add ports <portlist>
To delete a port from a virtual router, issue the following command:
configure vr <vr-name> delete ports <portlist>
The following is an example of removing all the ports on slot 3 from the default VLAN in the default
virtual router and adding them to the virtual router
helix :
configure vlan default delete ports 3:*
configure vr vr-default delete ports 3:*
configure vr helix add ports 3:*
Adding Routing Protocols to a Virtual Router
Unlike the default system virtual router, VR-Default, there are no resources allocated for routing
protocols when a user virtual router is created. You must add the routing protocols needed for your
virtual router before you attempt to configure them. When you add a protocol to a user virtual router, a
process is started to support the protocol.
