![]() Each of the routing domains are configured in separate Virtual Routing and Forwarding (VRF) domains on a pair of Catalyst 8500 Series Edge Platforms routers for high availability.ĮxpressRoute connectivity models can be categorized into two buckets: Partner model and Direct model. As shown in Figure 1, ExpressRoute circuits have multiple routing domains associated with them: Azure private peering, and Microsoft peering. The connectivity models are detailed at ExpressRoute connectivity models.ĮxpressRoute connections do not go over the public Internet, which allows ExpressRoute connections to offer more reliability, faster speeds, consistent latencies, and higher security than typical connections over the Internet. Connectivity can be from an any-to-any (IP VPN) network, a point-to-point Ethernet connection, through a virtual cross-connection via an Ethernet exchange or through a physical cross-connection directly to Microsoft’s router. The ExpressRoute solution enables layer 3 connectivity between your on-premises network and the Microsoft Cloud through a connectivity provider or directly to Microsoft’s routers. Although readers of this document are expected to have sufficient knowledge to install and configure the products used, the Cisco-Microsoft Joint Validated Design provides configuration details that are important to the deployment of this solution. It is important to note that this guide is not meant to be a comprehensive overview of the Catalyst 8500 Series Edge Platforms platform and routing technologies, see References section for platform and feature configuration guides.Ĭisco validation provides further confirmation of solution compatibility, connectivity, and correct operation for the on-premises deployment. This guide will focus on how to implement these best practices with Catalyst 8500 Series Edge Platforms configurations, recommend advanced features and services. To connect to Microsoft Azure services using ExpressRoute, Microsoft provides best practices for network security, optimize routing, asymmetric routing, and NAT. This document describes the steps required to extend your on-premises network into Microsoft Azure with ExpressRoute using the Cisco Catalyst 8500 Series Edge Platforms Series Routers. External references are provided wherever applicable, but readers are expected to be familiar with the technology, infrastructure, and enterprise security policies of the customer installation.Ĭisco-Microsoft Joint Validated Designs provide guidelines for creating an end-to-end solution that enable you to make informed decisions with the goal of successfully creating a hybrid cloud deployment. The intended audience for this document includes sales engineers, field consultants, professional services staff, IT managers, partner engineering staff, and customers deploying the Microsoft Azure ExpressRoute with Cisco Catalyst 8500 Series Edge Platforms. This JVD is a one stop guide that brings feature level clarity for the Cisco Catalyst 8500 Series Edge Platform configuration for extending your on-premises networks into Microsoft Cloud over a private connection as well as connectivity to Microsoft cloud services such as Microsoft Azure and Microsoft 365. To make the cloud deployment easier, Cisco and Microsoft have partnered to come up with a Joint Validated Design guide (JVD) using Cisco’s recently launched Catalyst 8500 Series Edge Platforms with Microsoft Azure ExpressRoute (ER) connectivity options. The role of Enterprise Edge platform is very important in establishing a reliable connection from Customer network to cloud end point. The reduced Total Cost of Ownership (TCO) and ability to elastically scale applications based on network demands along with guaranteed availability for workloads across multiple geographic regions are some of the key benefits driving this change. In today’s ever changing multi-cloud world, Enterprise Networks are adopting private and public cloud services to host business-critical applications.
