This document provides a sample configuration for a VPN routing and forwarding ( VRF ) instance under a generic routing encapsulation (GRE) tunnel interface. This lesson explains what VRFs are and how to configure VRF Lite on Cisco IOS routers. Dans cette vidéo, je vous explique brièvement la notion de VRF et je procède à la configuration simple de deux. This short video walks through the creation of a VRF , and explains one of the many reasons people use them.
Doug Downer demonstrates how to configure a VPN Routing and Forwarding ( VRF ) in an instance where a service provider needs to keep Internet services separate for two different clients on shared devices. In IP-based computer networks, virtual routing and forwarding ( VRF ) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. Because the routing instances are independent, the same or overlapping IP addresses can be used without conflicting with each other.
This method is useful in circumstances when you need to create multiple instances of a routing table on your router.
Some enterprises use VRF to seggrate their services like VOIP, wireless, geographical location and other varieties. Through the network setup below, we will see how to configure VRF and check if its really possible for duplicate ip addresses. We have customers in the figure connected to a Provider Edge . In Cisco terminology, deployment of VRFs without MPLS is known as VRF lite, and this article discusses a scenario where such a solution could come in handy. Assume the topology illustrated below is . Below is the configuration on the COMMON router that associates an OSPF routing process with each VRF. It is possible for a single CE device to serve multiple MPLS clients.
This requires traffic segregation to be extended to the CE device. The video looks at a scenario of multi- VRF CE device in Cisco MPLS VPN. BGP VRF Comme nous pouvons le constater sur le schéma ci-dessus, si nous ajoutons simplement les routes sur le routeur, il sera alors possible au.
Nous allons maintenant passer à la configuration de ce routeur. Notion_de_RD_(Route_Distinguisher). The VLAN interfaces for 1and 1are reachable to each other within the extranet virtual routing instance via layer-connectivity. The extranet vrf -instance VLAN interfaces are .
