Platform Considerations
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.

Configuring Virtual Routers
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)#
