Configuring a Virtual-Router Routing Instance

A virtual-router routing instance, like a VRF routing instance, maintains separate routing and forwarding tables for each instance. However, many of the configuration steps required for VRF routing instances are not required for virtual-router routing instances. Specifically, you do not need to configure a route distinguisher, a routing table policy (the vrf-export, vrf-import, and route-distinguisher statements), or MPLS between the service provider routers.

Configure a virtual-router routing instance by including the following statements:

description text;

instance-type virtual-router;

interface interface-name;

protocols { ... }

You can include these statements at the following hierarchy levels:

• [edit routing-instances routing-instance-name]
• [edit logical-routers logical-router-name routing-instances routing-instance-name]

The following sections explain how to configure a virtual-router routing instance:

• Configuring a Routing Protocol Between the Service Provider Routers
• Configuring Logical Interfaces Between Participating Routers
