Gre vrf

Hey buddy will you please get the information about the GRE VRF configuration of CISCO Networks so that I can go through that information easily?

As per your concern I will help you here to get the information about the GRE VRF configurations of CISCO Networks so that you can have idea about it.

Here is the information about the GRE VRF
Introduction
This document provides a sample configuration for a VPN routing and forwarding (VRF) instance under a generic routing encapsulation (GRE) tunnel interface.


Requirements
Configuring Multiprotocol Label Switching

MPLS Virtual Private Networks

Generic Routing Encapsulation Tunnel IP Source and Destination VRF Membership


Configure

In this section, you are presented with the information to configure the features

The configuration is set up in this way:

R1-CE and R2-CE are located in VRF BLUE.

R1-CE is also located in VRF GREEN through the use of a GRE tunnel to R3-PE.

R1-CE uses a static host route to get to R3-PE (tunnel destination), which ensures that recursive routing does not occur for the GRE tunnel

VRF BLUE and VRF GREEN are owned by two different companies, and no route leaks occur between them. in addition, the access control list (ACL) on the interface between R1-CE and R2-CE can be used to only permit GRE traffic between them.
