If DC2 site fails but DCI and DC1 site alive, traffic will enter DC1 side and traverse DCI to reach DC2 side servers. VXLAN would use flood and learn or BGP and OTV would use ISIS. Five Functional Facts about VXLAN Dec 3, 2013 Joel Knight 18 Comments It seems appropriate to write a FFF post about Virtual Extensible LAN (VXLAN) now since VXLAN is the new hotness in the data center these days. It uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number. Let’s see how we can setup a logical switch and a layer 2 bridge to accomplish this. VXLAN allows interconnection of a layer 2 Ethernet segment or layer 3 Services over a layer 3 network where the original layer 2 frame has a VXLAN header added and then placed in a UDP packet (MAC-in-UDP encapsu-lation). Within the UDP header, there is VxLAN header, within this header you have a VxLAN Network identifier (VNI) represented by 24 bits, it means that you have more than 16 million.

Let's talk about the other part of the story, VXLAN ( Virtual extensible LAN ) There are lot of questions on VXLAN, If there is OTV then why VXLAN ?. For mid-density 25GbE applications, CTC7148 supports 16x10G/25G+ 6x40G ports with advanced PFC/ ETS functionality, which is ideal for IP Storage application. There are design issues with running VXLAN as the DCI. This guide provides advice on deploying FlexFabric switches with EVPN Data Center Interconnect (EVPN DCI). As discussed in the EVPN for VXLAN Tunnels (Layer 2) example, EVPN and VXLAN can be enabled on VPLS or R-VPLS services in SR OS. VXLAN, Enhancements, and Network Integration SAFNOG 2014 – South Africa. ARISTA DESIGN GUIDE DATA CENTER INTERCONNECTION WITH VXLAN 6 INTRODUCING THE ARISTA NETWORKS DCI WITH VXLAN SOLUTION VXLAN was designed for the creation of logical layer-2 domains on top of an underlying IP network, initially to enable network virtualization in the data center. Additionally, the course will cover other data center concepts, including basic and advanced data center design options, Data Center Interconnect (DCI), EVPN multicast enhancements, and in introduction to data center automation concepts. Flood and Learn VxLAN may be used for rudimentary DCI. Now I'll show how to stretch Layer 2 using VXLAN as the tunneling protocol. This five-day course is designed to provide in-depth instruction on IP fabric and EVPN-VXLAN data center design and configuration. In the face of that sad reality, let's revisit what I wrote about layer-2 DCI over VXLAN. - Site A: VLAN100 mapped to DCI VNI 10100 - Site B: VLAN1100 mapped to DCI VNI 10100 - spine1&spine2 as mlag peers with logical VTEP - spine3 as single VTEP - ports for DCI configured as L3 routed (no switchport).

I just want to extend L2 between two datacenters, and looking for an alternative to flood and learn. Now I'll show how VMWare VMotion works over this same type of setup. VXLAN identifies individual layer-2 domains using a 24-bit virtual. It has a fabric builder for fabric initialization and does consistency monitoring. MAC Distribution Mode is an enhancement to VXLAN that prevents uknown unicast flooding. - Drop in VXLAN bridging only service, no requirement for VXLAN routing DCI to provide Layer 2 connectivity between geographically disperse sites VTEP VNI VTEP VNI Server migration POD interconnect for connectivity between DC's PODs. VXLAN EVPN Multi-Site architecture is a modern alternative to DCI technologies such as vPC, OTV, VPLS, or EoMPLS, and especially for interconnecting data center networks that are solely built on legacy technologies (for example, STP, vPC, or Cisco FabricPath). Pluribus' VCF fabric adds Layer 2 VXLAN capabilities for use in data center interconnect (DCI), extending the LAN to other locations. • What problems does VXLAN solve ? • What problems does BGP EVPN solve ? • Overview of BGP EVPN Route Types and associated use cases • Host IP/MAC distribution • IP Prefix route • Layer-3 DCI • L3 handoff between VXLAN-EVPN and MPLS-L3VPN to extend the layer-3 network connectivity across Data Centers over a WAN 2. Same statement could be made with L2TPv3 or EoMPLS, just to list few, they aim to extend L2 segments, but are not natively DCI solution per se. • Innovate in ASIC, power and cooling technologies to drive density and most efficient power footprint. Audio recording of a class lecture by Prof. L3 DCI has never been a challenge and requirement can be meet through IP/VPN or through many other ways (IPSec , GRE etc). VxLAN MB-BGP EVPN is taking a big step forward with its Control Plane and can be used for extending the Layer 2 across multiple sites. Overlay such as VXLAN; Provider Backbone Bridging (PBB) Section 2 – What is EVPN good for in the real world? In a nutshell, it carries entire Ethernet frames across an L3 infrastructure. This lab demonstrates how to: Practice VXLAN configuration for DCI on XR/NX-OS devices. この記事は某所で 2017/03/22 に書いた記事のコピーです。 そのため 2017/05/11 時点ではやや古い情報も含まれています。(2017/05 に GNS3 v2. Then I totally agree with Yves Louis who also said in one of his blog: "As of today, I will not consider the scalability and flexibility of the Host-based VxLAN sufficient enough for a valid DCI. Greetings, I've been reading about VxLAN BGP EVPN, and wondering if it's possible to deploy DCI without using VRFs. Supports Different Encapsulation Types - IP (VXLAN) & MPLS EVPN Cloud/NFV DC L3SL DCI Edge VPN Services IX WAN Metro Ethernet eVPN use-cases demonstrated in Public Multi-Vendor Routing Interop Test - April 2018 MPLS + SDN + NFV World Congress 2018. As a result, to provide a solution for DCI, VXLAN is integrated with EVPN. At a very high level, VXLAN can be deployed in multicast mode and with unicast. There are design issues with running VXLAN as the DCI. Provider Edge Configuration Independent of vCloud Director Platform 38 Figure 15. I don't think we'll see VXLAN support on ASR1k series simply because they are not positioned for DCI, though I admit it would be a pleasant surprise. txt) or read online for free. Building large-scale L2 networks, including stretched L2 networks, seems to be all the rage these days, driven in part by virtual machine mobility (aka vMotion in VMware vSphere environments or XenMotion in Citrix XenServer environments). To support DCI, the underlying network is also relied upon to ensure that traffic flows to and from the VMs are forwarded along the most direct path, before, as well as after migration; that bandwidth on all available links is. Depending on the type of hand-off to the outside network such as MPLS, LISP, layer-2, and so on, appropriate DCI configuration is required on the border device(s) and the connecting edge device(s) of the outside network. This document describes how Ethernet VPN (E-VPN) technology can be used to interconnect VXLAN or NVGRE networks over an MPLS/IP network.

This preface includes the following topics about the documentation: • Audien. The integration of NEO™ with Nutanix Prism Central provided a seamless DCI/VXLAN L2 stretch from host perspective. but when customer has layer2 vxlan connection from ASR1006 ,how can I do this. If DCI fails, traffic will continue being served from DC1 for stretched VLANs subnets, this implies move by other method those servers to the surviving side or at least shut them down. I just want to extend L2 between two datacenters, and looking for an alternative to flood and learn. A 24 bit identifier, the VXLAN Network Identifier (VNI), is used to designate individual interconnections. (dci)の際にも使用さ. The Arista VXLAN Hardware Gateway is capable of emulating layer-2 local area networks (LANs), so both point-to-point and point-to-multi-point logical layer-2 topologies are supported with the ability to deliver broadcast, multicast and unknown unicast traffic.

The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
