This article is the second post in a series that is all about EVPN-VXLAN and Juniper QFX technology. As a standards-based solution, BGP EVPN interoperates with other vendor solutions adhering to the same standard, and there is no vendor lock-in. Firstly, QFX5100 series doesn’t support EVPN-VXLAN inter-VXLAN routing, so I practice all IRB related topics on vMX devices. As we now, it’s possible to deploy anycast GW in Nokia (Alcatel-Lucent) SR OS using passive VRRP feature. Lastly, I’ll give an example configuration of L2VXLAN (EVPN Type-2) and L3VXLAN (EVPN Type-5). This is where VXLAN routing with EVPN comes in. Cisco is using BGP (Border Gateway Protocol) as the routing protocol, along with EVPN, to enable a complete control plane for VXLAN. Configuring IP prefix route advertisement If IGP routes are imported to the BGP-VPN IPv4 unicast address family and the corresponding VPN instance has a L3 VXLAN ID, the device advertises the imported routes as IP prefix advertisement routes. For each Section you will learn the Traffic flow, Control plane build, and then How Data Plane flows. 10. the way back • Symmetric* Uses an “symmetric path” from the Host towards Cisco Programmable Fabric with VXLAN, BGP-EVPN is a unique video title designed to teach you everything you need to understand how Data Center Networks can be built with VXLAN and BGP-EVPN. VXLAN EVPN – VxLAN is an overlay technology that encapsulates a Layer 2 frame into UDP header to extend your Layer 2 domain over a Layer 3 underlay infrastructure. VxLAN Routing and Control Plane on Nexus VXLAN/EVPN 21 RR RR V1 V2 V3 MP-BGP is the routing protocol for EVPN Carrying VLAN over EVPN-based network with VXLAN encapsulation using Juniper QFX5100 Switches.

Virtual Extensible LAN (VXLAN)* The platform offers native line-rate VXLAN routing. First we need to setup VNI 1000 and the Tenant1 routing table so we can import/export routes between the VRF and the global table. yml: clagd_vxlan_anycast_ip: 10. EVPN-VXLAN uses EVPN over a virtual extensible LAN (VXLAN) data plane, which is a simple alternative when MPLS is unavailable or unwanted in the core network. Controller-less - VXLAN bridging deployed to provide L2 connectivity across racks - VXLAN routing at the leaf layer to provide L3 connectivity between different BU VNIs - Single Enterprise so limited need for Layer 3 separation and scaled VRF - May need Layer 3 VRF separation for Production and Develops applications (ease migration process) VTEP VTEP VTEP Looking into EVPN and the route types (type 2 and 5) is my understanding correct. the way back • Symmetric* • Uses an “symmetricpath”from the Host towards the egressing port BGP-EVPN for the Data Center and L3 DCI November 30, 2015 • Every Tenant VRF will need a Vlan to be configured for VXLAN routing. net subscription. Intra-vxlan traffic has no issue. In VXLAN, such approach is deemed inefficient and the solution to it is to make possible every VTEP to route tenant’s traffic. 5 VTEP Devices which perform function to convert VLAN to VxLAN traffic or vices-versa are known as Virtual Tunneling End Points (VTEPs). In addition, the base systems with Cumulus Linux come with dynamic routing protocols and EVPN VXLAN functionality built-in. The ingress packet is a VXLAN packet on a routed nv overlay evpn # 2-Map VLAN to VXLAN vlan 100 vn-segment 10000 # 3-Create L2 VNI evpn vni 10000 l2 The EVPN address family carries both Layer-2 and Layer-3 reachability information, thus providing integrated bridging and routing in VXLAN overlay networks. • Encode source routing using MPLS label stack in the data-plane Concepts • Segment Routing envisions the network as a collection of ‘topological sub-paths’ – also called ‘segments’. Using this technique employs the VXLAN Routing directly on the ToR, using EVPN for both VLAN/VXLAN bridging as well as VXLAN and external routing. vxlan routing evpn. BGP EVPN L3 VNI (NX-OS 9) As an optimization for flood-and-learn process BGP was extended, so VTEPs could learn MAC addresses from BGP NLRI advertisements.

As of now, EVPN can be deployed with VXLAN, MPLS (RFC 7432) or PBB (RFC7623) Data planes. 9 ). VPNs and the associated tunneling technologies (L2TP, MPLS, DHCP, VPLS, Routing Protocols , etc. The following diagram depicts the network topology, link, esi, endpoint and Virtual Gateway Address (VGA) details. Does anyone know whether I EVPN (RFC 7432) Explained. I figured I’d take the opportunity to share some experiences specifically around inter-VXLAN routing. VxLAN/EVPN and Integrated Routing Bridging Summary. 0(3)I2(1) and later), VXLAN BGP EVPN is available only in the default routing mode. [2] [3] VXLAN is an evolution of efforts to standardize on an overlay encapsulation protocol. Well, the VXLAN/EVPN is running over IPv4 without any problem with HPE 5950. Do I need VXLAN to run EVPN? You need to leverage one of the Data plane tunneling protocols in order to carry traffic across the network. • Inter-VXLAN Routing Leaf/Access Layer • All Leafs share gateway IP and MAC for a Subnet (No HSRP) • A Host will always find its Gateway directly attached anywhere it moves VXLAN/EVPN Host Y VNI 30001 Host A VNI 30000 V1 V3 V2 *Requires EVPN Control-Plane. Multipath (routing options) Inter-VXLAN routing (L3 option of EVPN with VXLAN – distributed gateway) In this scenario we’ll deploy distributed gateway, which is one of the most useful options of EVPN. VLAN over EVPN-VXLAN Configuration > show configuration routing Does VXLAN EVPN inter-VXLAN routing work in data plane on Cisco Nexus 9000v? I followed steps documented, but the ping messages (as an example for data packets) don't pass between VXLANs. (Note Cumulus supports asymmetric model as well). In addition to owning their transport infrastructure, service providers are also in the business of offering managed IT and managed data center services to a large variety of customers. 1R1. VXLAN functions on Cisco Nexus 9300 platform switches are quickly evolving, with inter-VXLAN routing and EVPN control plane functions already planned. VxLAN commands used: Nv overlay evpn Interface-vlan Fabric forwarding anycast-gateway-mac Host-reachability protocol bgp L2vpn evpn Ip forward Associate-vrf Suppress-arp Ingress-replication In addition to discussing Layer 2 BUM traffic, this chapter talks about Layer 3 traffic forwarding in VXLAN BGP EVPN networks. EVPN-VXLAN Anycast Gateway. Together these technologies can enable VM live migration over the WAN, or long distance vMotion in VMware parlance, but they need to all work together effectively and this is where OVSDB, VxLAN routing and a new EVPN VXLAN Design Guide. After these enhancements become available, the VXLAN overlay design with Cisco Nexus 9300 platform switches can be further optimized and simplified. An iBGP EVPN session is established between all the VTEPs or with the EVPN RR to provide the full mesh connectivity required by iBGP peering rules. Thanks to this silicon integration- Mellanox is able to provide feature rich VXLAN EVPN functionality at an affordable price. VXLAN/EVPN: Standards based Overlay with Control-Plane Lukas Krattiger February 5, 2015 - 16 Comments Given the tremendous interest in VXLAN with MP-BGP based EVPN Control-Plane (short EVPN) at Cisco Live in Milan , I decided to write a “short” technology brief blog post on this topic. Integrated Routing and Bridging (IRB) VXLAN/EVPN based overlays follow two slightly different Integrated Routing and Bridging (IRB) semantics • Asymmetric • Uses an “asymmetricpath”from the Host towards the egressing port of the VTEP vs. BGP EVPN is used to communicate the VXLAN layer 3 routing information to the leafs. This improvement eliminates protocol state and optimizes traffic flows by implementing a distributed IP anycast gateway in the data center fabric. Part 4. Each pair of Leafs will form a VXLAN Tunnel Endpoint (VTEP). To view the L3 VXLAN ID of a VPN instance, use the display evpn routing-table command. We will start with the initial configuration of underlay components, such as MLAG and underlay BGP. By Sabyasachi Kar on September 11, A Layer 3 gateway is also used when there is a VxLAN to VLAN routing; that is the ingress packet is Helo all, I am working on some test setups in my lab around EVPN using VXLAN encapsulation on the QFX5100 (48T and 24Q, running 18. IPv6 works if I Set static /128 host routes to the switches. As we don’t need to configure underlay, cause it’s done, we go straight to the service part in this lab. Part 2. and the EVPN portion allows VXLAN to VXLAN routing (within a tenant at VxLAN/EVPN and Integrated Routing Bridging Summary. Equal-Cost Multipath (ECMP) Layer 3 routing. VXLAN And EVPN. VXLAN is one of the options, but it is not the only one. Visit our site and sign up for an Ethernet Virtual Private Network (EVPN) is a standards-based control plane for VXLAN defined in RFC 7432 and draft-ietf-bess-evpn-overlay that allows for building and deploying VXLANs at scale. Routing VXLAN is available in two architectures—centralized or distributed. Using ECMP with VXLAN routing is supported only on Broadcom Tomahawk and Mellanox Spectrum switches. In short: the 5100-48's (6) are leaf's, the 24q's spine (2). Intra-VXLAN traffic has no issue. Hello, I was looking for some hints about configuring anycast gateway in a VXLAN EVPN setup, i. Also we’ll enable IP services within EVPN to terminate to be able to perform inter-VLAN and/or inter-VXLAN routing The success criteria for the lab is that we are able to ping from VM in one L2 domain (VM1 and VM2) any VM in another domain (VM3 and VM4). The deployment of VXLAN bridging provides Layer-2 connectivity across the Layer-3 Leaf-Spine underlay for hosts. Does VXLAN EVPN inter-vxlan routing work in data plane on Nexus 9000v? I followed steps documented, but the ping messages don't pass between vxlans. yml: The VXLAN anycast IP is needed in BGP for EVPN and the same IP is shared between edge-1 and edge-2. 0. He added that the combination of BGP-EVPN with VXLAN can be used to define how the VXLAN tunnel endpoints map the MAC to IP address mappings for virtual machines. You can configure IPv4 and IPv6 distributed gateways and for IPv4 you can automatically distribute IPv4 host routes into e. - Traffic is VXLAN bridged at the Leaf to the Edge Node – Spine is routing the outer frame header - Edge Node decap the frame and forwards as a Q-tag to the DC core - DC Core routes the frame into the Dst VLAN, Dst tenant host learnt on the link to the Edge VxLAN has emerged as an alternative technology to VLANs, and EVPN has emerged at a better way to transport VMs over the WAN. Segment Routing Configuring VxLAN in EVE-NG Checkpoint - Pushing Policy, NAT , Policy Packages and database Versions - Part II This time everyone dropped whatever data center fabrics technology they were developing for the last decade and started shipping VXLAN and EVPN products. RFC 7432 was previously known as: draft-ietf-l2vpn-evpn. Based on the task above the following activities should be done: Turn created VPLS 10000123 into routed one cldemo-evpn-symmetric. This functionality is usually known as RIOT – Routing In and Out of the Tunnels; VXLAN-to-VXLAN bridging requires even more complex setup due to split-horizon rules controlling BUM flooding. If I want to replace underlay ospf/ibgp with ebgp only based on this famous draft draft-ietf-rtgwg-bgp-routing-large-dc-02, what will be the Evpn vxlan vni config looks like ( auto rt population no longer works in ebgp). VXLAN ROUTING AND BRIDGING. EVPN-VXLAN INTER-TENANT ROUTING ON JUNIPER QFX / MX. You can find the details in the Using VXLAN and EVPN in Multi-Pod and Multi-Site Fabrics part of Multi-Pod and Multi-Site Fabrics section of Leaf-and EVI: An EVPN instance spanning across the PEs participating in that EVPN MAC-VRF: A Virtual Routing and Forwarding table for MAC addresses on a PE for an EVI Ethernet Segment Identifier (ESI): The set of Ethernet links attaching a CE to a PE when the CE is multi-homed to two or more PE’s. Looking into EVPN and the route types (type 2 and 5) is my understanding correct. Segment Routing Configuring VxLAN in EVE-NG Checkpoint - Pushing Policy, NAT , Policy Packages and database Versions - Part II This includes VTEPs, ingress replication (AKA head end replication), OSPF in the underlay, VNI’s and encapsulation (tunnels) in the overlay, BGP, VRF’s, Integrated routing and bridging (IRB), ARP suppression, and anycast gateway, all on real Cisco Nexus (NX OS) 9000 switches. When configuring VXLAN VNIDs, the network administrator must specify that EVPN is used as a control plane. Step 4: Add your Clients and verify the Setup. View Building Data Centers with VXLAN BGP EVPN A Cisco NX-OS Perspective. It uses the distributed architecture with symmetric IRB model. Part 1. the vPC peer switch holds down the vPC links and SVIs until the routing Configuration of overlay network infrastructure (EVPN + VXLAN) for IP routing. Join today to get access to thousands of courses Top Posts & Pages. Ethernet segments MUST have a unique non-zero identifier, the ‘Ethernet Segment Identifier’. First and foremost — it seems that there are several ways to skin the cat with routing out from a VXLAN EVPN tenant to the rest of the world.

BGP EVPN L3 VNI (NX-OS 7) VXLAN. They don’t all need to be running VTEPs. An example is the spine switches in the spine/leaf topology. Some vendors can achieve VXLAN Routing on Trident 2 chipset, by doing a dual pass in the chip. BRKDCN-2020 BGP next hops advertised in EVPN updates point to egress Label Switch Router (LSR) or VXLAN Tunnel Endpoint (VTEP); Underlying routing protocol computes the best path(s) to BGP next hops; A BGP router that changes the BGP next hop in an EVPN update must also perform data plane decapsulation and re-encapsulation. BGP EVPN L3 VNI (NX-OS 9) Traditionally, routing is done in Distribution layer, so a frame must to be bridged towards a gateway. For Layer 3 forwarding or routing, the presence of a first-hop default gateway is necessary. This demo shows one approach of running VXLAN Routing with EVPN. Regardless of the traffic patterns (east–west or north–south), the hair-pinning of traffic is completely eliminated. The RD & RT in the VRF instance is needed to distinguish between the VPNs. 10 BGP routing table information for VRF default, address family L2VPN EVPN Inter-VXLAN routing (L3 option of EVPN with VXLAN – distributed gateway) In this scenario we’ll deploy distributed gateway, which is one of the most useful options of EVPN. VXLAN EVPN Fabric and automation using Ansible sh bgp l2vpn evpn 172. RFC 5512 and draft-ietf-bess-evpn-inter-subnet-forwarding-00 define how MP-BGP Network Layer Reachability Information (NLRI) carries VXLAN encapsulation as well as L2/L3 forwarding information details to provide an integrated routing and bridging solution within the Data Center site. EVPN is an extension to the MP-BGP address family which allows to carry VXLAN/MAC information in the BGP routing updates. BGP EVPN Multihoming: The STP root always must be the VXLAN Fabric.

EVPN Control and Data Planes Inter-VXLAN Routing Another function that MP-BGP EVPN provides is the ability to route VXLAN packets. Routing into and out of the EVPN network BGP EVPN relies on BGP (RFC 4271) and its MP-BGP extensions (RFC 4760). 4 CONTENTS . Key Benefits of Cumulus Linux and BGP EVPN Standards-based BGP EVPN BGP is already the preferred routing protocol within the datacenter. VXLAN tunnel end-points (VTEPs) can optimally exchange data across the fabric, completely abstracting the overlay network from the series of underlay /31 point-to-point links. Inter-VXLAN routing (L3 option of EVPN with VXLAN – distributed gateway) In this scenario we’ll deploy distributed gateway, which is one of the most useful options of EVPN. For example, you may have a shared-services tenant that needs to be accessed by a number of different customer tenants whilst not allowing reachability between customer tenants. protocols {bgp {group interop {type internal; local-address 10. The focus in this design guide is VxLAN as the protocol for the data-plane encapsulation for the overlay tunnels, and the functionality of the Multiprotocol BGP (MP-BGP) VXLAN functions on Cisco Nexus 9300 platform switches are quickly evolving, with inter-VXLAN routing and EVPN control plane functions already planned. Students will learn the fundamentals of the overlays technologies, modern Data Center approaches like spine and leaf architecture. (2) The PE then sends the MAC Address routing information to the MP-BGP EVPN RR.

Multipath (routing options) Thanks to this silicon integration- Mellanox is able to provide feature rich VXLAN EVPN functionality at an affordable price. Great post Lukas!. x. 0/24). 75fa. VXLAN EVPN Overview VXLAN Ethernet Virtual Private Network is a standards-based overlay solution that deploys VXLAN fabric with a Border Gateway Protocol (BGP)-based control plane that specifies the BGP EVPN control plane for overlays. As I mentioned in the post 28 – Is VxLAN Control Plane a DCI solution for LAN extension, VxLAN/EVPN is taking a big step forward with its Control Plane and could be used potentially for extending Layer 2 segments across multiple sites. 27 This Course enables you to learn VXLAN in deep details like VXLAN perquisite, VXLAN Bridging, VXLAN Routing, VXLAN over Multicast and also how to configure VXLAN on MPBGP-EVPN scenario. evpn可以作为vxlan的控制层面,evpn技术为vxlan的l3优化也提出了解决方法。 下面看看EVPN怎么完成的VXLAN routing,首先看一下EVPN提出的数据层面的优化,接着介绍EVPN作为控制层面如何支持优化过的数据层面。 VXLAN EVPN Multi-Fabric with External Active/Active Gateways. 70; family evpn BGP EVPN Multihoming: The STP root always must be the VXLAN Fabric. 0/16 + the host routes to this shared border. This post shows how the intra-L2VNI and Inter-L2VNI routing inside VXLAN is donw with RT. 32. 1 The VXLAN anycast IP is needed in BGP for EVPN and the same IP is shared between edge-1 and edge-2. vxlan routing evpn I’ve recently started working on a project focused on EVPN-VXLAN based on Juniper technology. In the older models of VXLAN with multicast as the control plane, a routing block had to be used
