Juniper JUNOSE SOFTWARE FOR E SERIES 11.0.X - BGP AND MPLS CONFIGURATION GUIDE 2009-12-30 Configuration Manual page 467

If you are not in the context of the virtual router that has the VRF, you access the
VRF as follows:
The following commands illustrate one way to configure OSPF; you can configure
RIP and IS-IS similarly:
At this point you proceed with the IGP configuration for the VRF.
Configuring the IGP Outside the VRF Context
The RIP and OSPF protocols also enable you to specify a VRF and configure the
protocol without actually entering the VRF context.
For example, for OSPF you might issue the following command and then complete
OSPF configuration tasks for VRF A:
For RIP, you create the RIP process, specify the address family for the VRF, and
specify redistribution of BGP routes for VRF A:
At this point you proceed with RIP configuration for the VRF. For information about
configuring IS-IS, OSPF, or RIP as the IGP, see the JUNOSe IP, IPv6, and IGP
Configuration Guide. For information about configuring BGP as the IGP, see
"Configuring BGP Routing" on page 3.

Use to access a VRF to configure it with an IGP to learn routes from a CE router.
To access the VRF from its VR context (in this example, the default VR):
host1(config)#virtual-router :vrfsouthie
host1:default:southie(config)#
To access the VRF from the context of a different VR:
host1(config)#virtual-router boston:southie
host1:boston:southie(config)#
