Chapter 3 Configuring Remote Access to MPLS VPN
Configuration Tasks for RA to MPLS VPN
Example 3-10 Creating a VRF Configuration for a VPN
ip vrf common
rd 100:1000
vpn id 100:1000
route-target export 100:1000
route-target import 100:1000
Note For more information about creating VRFs, see the “Configuring Virtual Routing and Forwarding
Instances” section on page 3-13.
Associating a VRF Configuration for a VPN with a Virtual Template Interface
After you create a VRF configuration for a VPN, associate the VRF with a virtual template interface.
The virtual template interface is used to create and configure a virtual access interface (VAI).
To associate a VRF, enter the following commands beginning in global configuration mode:
Example 3-11 Associating a VRF Configuration for a VPN with a Virtual Template Interface
interface Virtual-Template1
ip vrf forwarding common
ip unnumbered Loopback1
Note • For more information about configuring a virtual template interface, see the “Configuring a Virtual
Template Interface” section on page 3-17.
• For more information about creating and associating VRFs, see the “Configuring Virtual Routing
and Forwarding Instances” section on page 3-13 and the “Associating VRFs” section on page 3-13.
Step 3
Router(config-vrf)# vpn id
