You can define your own network space, and control how your network and the Amazon EC2 resources inside your network are exposed to the Internet.
The L2 switch is enabled with IGMP snooping, and the domain is scoped to groups in the 239.1.0.0/16 range. A VPC is a software-defined network (SDN) optimized for moving massive amounts of packets into, out of and across AWS regions. This document introduces some best practices … Back to Cisco Data Center Section Cisco has made the Nexus with the intent to prevent bridge forwarding looping and duplicate packets, to make Layer 2 work correctly without needing Spanning Tree Protocol (STP) to do so. We also provided useful show commands needed to validate and troubleshoot the status of the vPC. Both platforms support the common Layer 3 unicast and multicast routing protocols (RIP, EIGRP, OSPF, BGP, IS-IS, PIM, MSDP). So the vPC system address in our example will be 0023.04ee.be17.
You cannnot build a vPC where one end of the port channel is split across two VDC’s of one Nexus switch. The tenant of Figure 5-14 wishes to use a private multicast domain within the private zone of the network for back-end services. The vPC system MAC address has a fixed part = 0023.04ee.be.xx and the two last digits (xx) are taken from vPC domain ID. Our example vPC domain has ID 23, which HEX format is 17. FWIW, Cisco's Design and Configuration Guide: Best Practices for Virtual Port Channels (vPC) on Cisco Nexus 7000 Series Switches document has a section called Best Practices for Multicast and vPC View entire discussion ( 7 comments) the other Cisco Nexus 5000 Series Switches it supports 12 fabric extenders. Amazon VPC enables you to build a virtual network in the AWS cloud - no VPNs, hardware, or physical datacenters required. The Nexus switch will use the vPC link as a normal layer 2 trunk if it's the only way to get the traffic to the destination. List of vPC Best Practices. VPC peer switches will automatically create a unique vPC system MAC address. Finally, the vPC configuration guide and best practices section showed how to configure vPC and apply optional configuration commands to increase resiliency and reduce disruptions in vPC operations. A transit gateway scales elastically based on the volume of network traffic. This is a private range and can overlap with any range in the public or shared-public zones, as the domain ends at the inside L3 router. The vPC domain ID should be unique within its L2 domain. The vPC role priority should be configured so the primary device is known. Your packet … For more information on ACI Naming Best Practices, check out the ACI Naming Best Practices article. You can find the configuration window under Fabric > Access Policies > Switch Policies > Policies > Virtual Port Channel default. Amazon Virtual Private Cloud Transit Gateways Resource attachments How transit gateways work A transit gateway acts as a Regional virtual router for traffic flowing between your virtual private clouds (VPC) and VPN connections. Name the vPC peer-grouping name. If OTV is contemplated, the vPC domain ID should be unique across all datacenters. Cisco FabricPath Best Practices What You Will Learn Cisco® FabricPath has been deployed and running in the field since end of 2010, and thousands of customers have now acquired Cisco FabricPath licenses for their networks. I choose something simple, like “Leaf201_202”. If the Cisco Nexus 5500 platform is used in conjunction with the Layer 3 engine, at the time of this writing Cisco NX-OS 5.0(3)N1(1a) supports a maximum of eight fabric extenders per Cisco Nexus 5500 platform. Cisco vPC Best Practices and Failure Scenarios Cisco's Virtual Port Channel (vPC) technology is developed for Cisco NX-OS software for Cisco Nexus switches like Nexus 7000, Nexus 5000 (with or without Fabric Extender Nexus 2000), etc.
