If you already have seen my lesson for PE-CE RIP then you can skip to the EIGRP between PE and CE routers section as the configuration of the service provider network is exactly the same. Layer 3 VPNs Configuration Guide. Verifying the MPLS Layer 3 VPN Configuration page 22-46.
If you are looking for an MPLS Tutorial or step by step mpls configuration examples this basic MPLS VPN configuration example will guide you from configuring the first router to a 3 router MPLS core with 2 external sites. ManualLayer-3 MPLS VPN example. For example you can create an IP prefix list or an as-path filter to define an IP prefix or IP prefix range and use that prefix list or as-path filter in a match clause for the route map.
Heres the topology I will use. MPLS switching configuration in Cisco IOS Release 150SY is. To configure MPLS Layer 3 VPN functionality on a router running Junos OS you must enable support on the provider edge PE router and configure the PE router to distribute routing information to other routers in the VPN as explained in the following steps.
Benefits of BGP MPLS Layer 3 VPN. In this lesson well take a look how we can use EIGRP as the PE-CE routing protocol for MPLS L3 VPN. Layer 3 VPNs Configuration Guide Cisco IOS Release 15MT.
Heres the topology we will use. Internet providers who have an existing Layer 2 network may choose to use these VPNs instead of the other common MPLS VPN Layer 3. A simpler configuration would work as well – one where there is a BGP session between B and D and C is not running BGP at all.
In our previous blog article weve discussed the benefits and the fundamental principles of BGPMPLS L3 VPNs. Layer 3 VPNs Configuration Guide Cisco IOS Release 15MT. BGPMPLS Layer 3 VPNs Practical Configuration.

What you need for. This sample configuration shows LAN CE-facing interfaces. Note that route reflection here is used for the sake of an example.
If are you looking for an explanation of MPLS then I would advise you read the What is MPLS post first before attempting this lab. Above we have five routers where AS 234 is the service provider. However because the tunnel information is maintained at both PE routers.
They solve the scalability issue of conventional IPSec VPNs deployed in a full-mesh model reducing the configuration overhead while interconnecting many sites. Note If you use a Layer 3 VLAN interface as the MPLS uplink through a Layer 2 port peering with another MPLS device then you can use another Layer 3 VLAN interface as the VRF interface. Remote access applications such as the Remote Authentication Dial-In User Service RADIUS and Dynamic Host Configuration Protocol DHCP can use the MPLS VPN ID feature to identify a VPN.
MPLS VPN VRF Selection Using Policy-Based Routing. Layer 3 VPNs Configuration Guide. Benefits The MPLS VPN ID feature provides the following benefits.
This is a kind of putting it all together setup. We have covered the definition of the basic terms such as the Route Distinguisher RD the Route Target RT and the VPN-IPv4. In that example I have redundant P and PE routers but I didnt use MPLS there.
