Virtual Routers
ExtremeWare XOS 11.3 Concepts Guide

Configuring the Routing Protocols and VLANs
Once the virtual router is created, the ports are added, and support for any needed routing protocols is
added, you can configure the virtual router. To simplify configuring the user virtual routers, the concept
of a virtual router configuration domain was added (instead of adding a virtual router keyword to
every command in every routing protocol). Virtual router commands are applied to the current
configuration domain. The virtual router commands consist of all the BGP, OSPF, PIM and RIP
commands, as well as the
create vlan
and
delete vlan
commands. Other commands apply to the
switch as a whole.
To enter a virtual router configuration domain, use the following command:
virtual-router {<vr-name>}
For example, to enter the configuration domain for the virtual router helix , your CLI session would look
similar to this:
* BD10K.13 # virtual-router helix
* (vr helix) BD10K.14 #
The CLI prompt displays the virtual router configuration domain.
Use the
virtual-router
command with no virtual router name, or use the name VR-Default to return
to the default configuration domain.
Now you can create VLANs, using the following command:
create vlan <vlan_name> {vr <vr-name>}
If you do not specify a virtual router in the
create vlan
command, the VLAN is created in the virtual
router of the current configuration domain.
NOTE
All VLAN names and VLAN IDs on a switch must be unique, regardless of the virtual router they are created in. You
cannot have two VLANs with the same name, even if they are in different virtual routers.
You can also configure routing protocols, by using the standard ExtremeWare XOS commands. The
routing configurations of the different virtual routers are independent of each other.
Virtual Router Configuration Example
In the following example:
●
The user virtual router helix is created
●
Ports are removed from the VLAN Default and the virtual router VR-Default
●
Ports are added to the virtual router helix
●
OSPF is added to the virtual router helix
●
The configuration domain is set to helix , so that subsequent virtual router commands affect the
virtual router helix
