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. 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.
What you need for. 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. This sample configuration shows LAN CE-facing interfaces.
In this lesson well take a look how to configure a MPLS Layer 3 VPN PE-CE scenario. Benefits The MPLS VPN ID feature provides the following benefits. Layer 2 VPNs uses the Label Distribution Protocol LDP to communicate between PE routers and established a virtual circuit providing the customer one or more private point-to-point connection.
