Virtual routers are supported on all E Series routers.
For information about the modules supported on E Series routers:
See the ERX Module Guide for modules supported on ERX7xx models, ERX14xx models,
and the ERX310 router.
See the E120 and E320 Module Guide for modules supported on the E120 and E320
routers.
For more information about virtual routers, VPNs, or VRFs, consult the following resources:
JunosE Release Notes, Appendix A, System Maximums—Refer to the Release Notes
corresponding to your software release for information about maximum values.

RFC 4364—BGP/MPLS IP Virtual Private Networks (VPNs) (February 2006)
This section provides examples of some of the more common virtual router tasks.
There are different uses of the virtual-router command. You can create or access VRs
and VRFs in Global Configuration mode or map a VR to a domain map in Domain Map
Configuration mode. After you have created a VR, you can continue to work in different
command modes and configure the same user interface parameters as before the virtual
router was created.
For information about the many VR tasks you can configure, see the related chapter; for
example, JunosE IP, IPv6, and IGP Configuration Guide or JunosE BGP and MPLS
Configuration Guide.
To configure a virtual router:
Create and name a VR in Configuration mode.
host1(config)#virtual-router western
host1:western(config)#
Create a VRF to provide forwarding information to your router. In this example, the VRF
created is in context with the VR created above.
host1:western(config)#ip vrf eastern
Proceed with new VRF creation? [confirm]
host1:western(config-vrf)#virtual-router:eastern
host1:western:eastern(config)#
