Example 4: MPLS Virtual Private Networks
RouterB(config)# access-list 50 permit 65.0.0.0
RouterB(config)# access-list 60 permit 66.0.0.0
RouterB(config)# access-list 70 permit 67.0.0.0
The following example shows how to configure several interfaces to classify packets based on the IP
precedence and QoS group ID:
interface serial5/0/0/1:0
ip address 200.28.38.2 255.255.255.0
bgp-policy source ip-prec-map
no ip mroute-cache
no cdp enable
frame-relay interface-dlci 20 IETF
interface serial6/0/0/1:0
ip address 200.28.28.2 255.255.255.0
bgp-policy source qos-group
no ip mroute-cache
no cdp enable

Example 4: MPLS Virtual Private Networks
MPLS can be used to create IP-based VPNs. MPLS VPNs offer all of the value of traditional VPNs,
including reduced costs and enhanced security. In addition, because MPLS VPNs are created in Layer
3, they are more scalable, easier to configure, and easier to manage than Layer 2 VPNs.
Perform the tasks in the following sections to configure MPLS Virtual Private Networks (VPNs):

Defining a VPN
Enter VRF configuration mode, define the VPN routing instance by assigning a VRF name, and create
routing and forwarding tables.
Router(config)# ip vrf go_fast_internet_company
Router(config-vrf)# rd 200.28.28.40:42
Create a list of import or export route target communities for the specified VRF.
Router(config-vrf)# route-target import 200.28.28.40:43
Associate the specified route map with the VRF and with an interface or subinterface.
Router(config-vrf)# import map go_fast
Router(config-if)# ip vrf forwarding go_fast_internet_company
