to identify the VPNs that it wants to receive the updates. See JUNOSe BGP and MPLS
Configuration Guide.
Platform Considerations
Virtual routers are supported on all E Series routers.
For information about the modules supported on E Series routers:
â– See the ERX Module Guide for modules supported on ERX7xx models, ERX14xx
models, and the ERX310 router.
â– 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:
â– Create and name a VR in Configuration mode.
host1(config)#virtual-router western
host1:western(config)#
â– 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
