Introduction

IntroductionThe Cisco Intelligent WAN (IWAN) solution provides design and implementation guidance for organizations looking to deploy wide area network (WAN) transport with a transport-independent design (TID), intelligent path control, application optimization, and secure encrypted communications between branch locations while reducing the operating cost of the WAN. IWAN takes full advantage of cost-effective transport services in order to increase bandwidth capacity without compromising performance, reliability, or security of collaboration or cloud-based ap-plications.

This document provides the available configuration files for the products used in the Intelligent WAN Deployment Guide and the Intelligent WAN advanced series of guides.

The advanced guides are as follows:

• IWAN High Availability and Scalability Deployment Guide

• IWAN Multiple Data Center Deployment Guide

• IWAN Multiple Transports Deployment Guide

• IWAN Multiple VRF Deployment Guide

• IWAN Public Key Infrastructure Deployment Guide

• IWAN NetFlow Monitoring Deployment Guide

• IWAN Remote Site 4G LTE Deployment Guide

This guide is a companion document to the deployment guides, serving as a reference for engineers who are evaluating or deploying the IWAN solution.

This guide describes two base IWAN design models and three advanced IWAN design models.

The first design model is the IWAN Hybrid, which uses MPLS paired with Internet as WAN transports. In this design model, the MPLS WAN can provide more bandwidth for the critical classes of services needed for key ap-plications and can provide SLA guarantees for these applications.

The second design model is the IWAN Dual Internet, which uses a pair of Internet service providers to further reduce cost while maintaining a high level of resiliency for the WAN.

The first advanced design builds on previous design models by adding hub borders routers for horizontal scaling at a single data center. This design also has an option to add a second hub master controller (MC) at a single data center for high availability.

Introduction

The second advanced design builds on previous design models with data center redundancy. The multi-data center or the transit site support feature enables organizations to scale their network infrastructure and load-balance the traffic when required. The first version of this advanced design uses a data center interconnect (DCI) link between the hub and transit sites.

Introduction

The third advanced design model is a multiple transport option called IWAN Dual Hybrid with Path of Last Resort (PLR). This model has two MPLS transports, two Internet transports, and a fifth transport used as the final option when the other four are not available. The model is not limited to two MPLS, two Internet and one PLR transport, but this specific design is used to show the underlying principles for multiple transports. The multiple transport design can be used with any of the previous design models.

You can add multiple WAN transports with new border routers or the Multiple Tunnel Termination (MTT) feature for each transport, depending on the scaling requirements.

Introduction

The fourth advanced design model is a multiple transport option called IWAN Dual Hybrid with PLR and Multiple VRFs. This model adds virtual routing and forwarding instances for isolating end-to-end traffic among multiple independent networks inside the same data center (DC). Similarly, at the remote location, devices in each VRF co-exist inside the same physical hardware as the common employee network. The model is not limited to three VRFs, but this specific design is used to show the underlying principles for multiple VRFs. The multiple VRF design can be used with any of the previous design models.

The hub-site and transit-site are connected by a DCI link. Both sites are further connected to the remote sites over multiple WAN transports.

IWAN Hybrid Design Model for EIGRP—WAN Aggregation

IWAN Hybrid Design Model for EIGRP—WAN AggregationPerformance Routing Version 3 (PfRv3) consists of two major Cisco IOS components: an MC and a border router (BR). The MC defines the policies and applies them to various traffic classes that traverse the BR systems. The MC can be configured to learn and control traffic classes on the network.

There are two different roles a device can play at the WAN aggregation site of a PfRv3 configuration:

• Hub master controller—The hub MC is the MC at the primary WAN aggregation site. This is the MC device where all PfRv3 policies are configured. It also acts as MC for that site and makes path-optimization decision. There is only one hub MC per IWAN domain.

• Hub border router—This is a BR at the hub MC site. This is the device where WAN interfaces terminate. There can be only one WAN interface on the device. There can be one or more hub BRs. On the Hub BRs, PfRv3 must be configured with:

◦ The address of the local MC.

◦ The path name on external interfaces.



This section includes configuration files corresponding to the IWAN hybrid model using EIGRP, as referenced in the figure below.

The following table provides the loopback IP addresses for the remote site devices in the IWAN hybrid design model with multiple next hops (MNH) and MTT.

IWAN Dual Hybrid with PLR and MTT Design Model for BGP—WAN Aggregation with DCI

IWAN Dual Hybrid with PLR and MTT Design Model for BGP—WAN Aggregation with DCIPerformance Routing Version 3 consists of two major Cisco IOS components: an MC and a BR. The MC defines the policies and applies them to various traffic classes that traverse the BR systems. The MC can be configured to learn and control traffic classes on the network.






This section also shows a second data center acting as a transit site with a transit MC and transit BRs.

• Transit master controller—The transit MC is the MC at the transit site. There is no policy configuration on this device. It receives policy from the hub MC. This device acts as MC for that site for making path optimization decisions. The configuration includes the IP address of the hub MC.

• Transit border router—This is a BR at the transit MC site. This is the device where WAN interfaces terminate. There can be only one WAN interface on the device. There can be one or more transit BRs. On the transit BRs, PfRv3 must be configured with:

◦ The address of the transit MC.


◦ The path ID on external interfaces.



Finally, this section includes configuration files corresponding to the IWAN dual hybrid model with PLR and MTT using BGP on the WAN and OSPF on the LAN, as referenced in the figure below. There is a DCI link between the hub and transit site.

The MC defines the policies and applies them to various traffic classes that traverse the BR systems. The MC can be configured to learn and control traffic classes on the network.






This section also shows a second data center acting as a transit site with a transit MC and transit BRs.






In order to enable inter-VRF route leaking, a Cisco firewall is configured with static routes. It is attached to the hub-site WAN distribution switch, and a very basic configuration is included here as a reference only.



Finally, this section includes configuration files corresponding to the IWAN dual hybrid model with PLR and Multi-VRF using BGP on the WAN and OSPF on the LAN, as referenced in the figure below.

IWAN Dual Hybrid with PLR and Multi-VRF Design Model for BGP—Remote Sites

IWAN Dual Hybrid with PLR and Multi-VRF Design Model for BGP—Remote SitesPerformance Routing Version 3 consists of two major Cisco IOS components: an MC and a BR. The MC defines the policies and applies them to various traffic classes that traverse the BR systems. The MC can be configured to learn and control traffic classes on the network.


• Branch master controller—The branch MC is the MC at the branch-site. There is no policy configuration on this device. It receives policy from the hub MC. This device acts as MC for that site for making path-optimi-zation decision. The configuration includes the IP address of the hub MC.


The following tables provide the loopback IP addresses for the remote site devices in the IWAN dual hybrid with PLR and Multi-VRF design model.
