Configure a VPN Routing Instance on the PE Routers

You need to configure a routing instance for each VPN on each of the PE routers participating in the VPN. The configuration procedures outlined in this section are applicable to Layer 2 VPNs, Layer 3 VPNs, and VPLS. The configuration procedures specific to each type of VPN are described in the corresponding sections in the other configuration chapters.

To configure routing instances for VPNs, include the following statements:

description text;

instance-type type;

interface interface-name;

route-distinguisher ( as-number:number | ip-address:number );

vrf-import [ policy-names ];

vrf-export [ policy-names ];

vrf-target {

    export community-name;

    import community-name;

}

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]

To configure VPN routing instances, you do the following:

• Configure the Description
• Configure the Instance Type
• Configure Interfaces for VPN Routing
• Configure the Route Distinguisher
• Configure Policy for the PE Router's VRF Table
• Configure BGP Route Target Filtering
