Juniper evpn multihoming Broadcast, unknown unicast, and multicast, commonly known as BUM (Broadcast, Unknown unicast, and Multicast) traffic, is handled natively by EVPN and eliminates the need for Spanning Tree Protocols (STP/RSTP). This module describes how to configure a CE and two PEs to take part in a multihomed EVPN. Figure 1 illustrates an EVPN topology with active-standby multihoming to a single PE device. The following subfeatures are supported: QFX10000 switches over an MPLS EVPN core only support the default-switch routing instance. 40. 4R1, QFX10000 switches support multihoming for EVPN MPLS. Oct 16, 2023 · See the EVPN Multihoming Implementation section of the EVPN Multihoming Overview document for additional information related to ESI types. This section discusses Ethernet Segment Identifiers (ESIs), ESI Types, and LACP in EVPN LAGs. Collapsed Core EVPN-VXLAN with EVPN Multihoming Campus This example shows how to configure Ethernet VPN (EVPN) with MPLS for multihomed customer edge (CE) devices in active-standby redundancy mode. Juniper Networks campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that you can deploy on any campus. This example shows how to configure active-standby multihoming in an Ethernet VPN (EVPN) fabric with MPLS. It is intended as a resource to help readers understand EVPN LAG capabilities in different contexts. This Network Configuration Example (NCE) shows how to set up a collapsed spine data center fabric that lets you use your existing Layer 2 top-of-rack switches in place of leaf devices. Note : Depending on what mode the router is operating in, a full system reboot is required. This article won’t explain how VXLAN or EVPN works, as it focuses on the configuration. But i couldnt fig Log in to ask questions, share your expertise, or stay connected to content you value. Oct 9, 2023 · Collapsed Core EVPN-VXLAN with EVPN Multihoming Campus Network Scaling Data | 47. IMPORTANT: If the router has dual routing engines, make sure both routing engines are configured and operating in Enhanced IP mode. This is what i'm seeing, sometimes both PEs will advertise the type2 routes and sometimes they won't. The module also describes the contents of the Type 4 Ethernet Segment route and explains how the Type 4 route prevents layer 2 loops, using the designated forwarder election. You can configure multihoming in active-standby redundancy mode in an Ethernet VPN (EVPN) fabric with MPLS. rfc-editor. This example shows how to configure Ethernet VPN (EVPN) for multihomed customer edge devices in the active-active redundancy mode, so the Layer 2 unicast traffic can be load-balanced across all the multihomed links on and toward the CE device. This provides a layout of the EVPN Multihoming topology as configured and can be used as a source of truth with respect to device interconnectivity parameters: Supported Platforms Collapsed Core. This example shows how to configure the Link Aggregation Control Protocol (LACP) on multihomed customer edge (CE) and provider edge (PE) devices in an Ethernet VPN (EVPN) active-active multihomed network. A Data Center Service Provider (DCSP) hosts the data center for its multiple customers on a common physical network. Junos OS on QFX Series switches support Enterprise style configuration and Service Provider style configuration. We’ll go through the basics of configuring Juniper switches with VXLAN as the data plane, and EVPN as the control plane. This example shows how to configure an active-active multihomed customer edge (CE) devices and provider edge (PE) devices in an Ethernet VPN (EVPN). An EVPN instance (EVI) is not supported. This architecture merges the core and distribution layers into a single switch. The steps in this example set up: The designated forwarder (DF) manages broadcast, unknown unicast, and multicast (BUM) traffic to prevent loops and ensure efficient traffic distribution. This section provides an overview of the Juniper EVPN-VXLAN reference architectures and the role of EVPN LAGs in these architectures. 2. Noticing some strange behaviour on some VQFXs acting as a PE routers to a dual homed CE. Overview of a Collapsed Core with EVPN Multihoming in a Campus Network. Managing the EVPN-VXLAN Fabric. . EX4100* EX4300-MP; EX4400 This module describes Type 1 Ethernet Autodiscovery Per-Ethernet Segment routes and explains how Type 1 Per-Ethernet Segment routes prevent layer 2 loops. org/rfc/rfc8365) that is common across campuses and data centers. Nov 21, 2023 · The user can now access the EVPN Multihoming Campus Fabric: Notice the Connection Table option at the upper right corner. An Ethernet segment identifier (ESI) is a 10-octet integer that identifies this segment. In a multihomed setup - should each PE advertise type2 routes to the VTEP? I have a pretty basic setup. This section introduces some commonly-used features in EVPNs that are using EVPN LAGs. This network configuration example (NCE) describes how to configure and manage a campus network using EVPN-VXLAN on a collapsed core architecture with EVPN multihoming (also called ESI-LAG). Link aggregation provides the technology to bundle interfaces and to increase bandwidth in a data center by adding new links to bundled interfaces. How to Configure a Campus Network using EVPN Multihoming. The PE routers can include an MPLS edge switch (MES) that acts at the edge of the MPLS infrastructure. EVPN Multihoming Problem with IGMP-Snooping, Multihoming Problem with Selective Forwarding, BGP Type-7 Join-Sync Route to Synchronize IGMP State in Multihoming PEs, Non-DF to Originate Type-6 SMET Route for Better Convergence, Summary - IGMP Join-Sync and Multicast Forwarding, Problem with IGMPv2 Leave, BGP Type-8 Leave-Sync Route to Reconcile IGMP State, Putting It All Together for Optimized This configuration example uses the following devices: When a customer edge (CE) device in an Ethernet VPN-Multiprotocol Label Switching (EVPN-MPLS) environment is multihomed to two or more provider edge (PE) devices, the set of Ethernet links that connect the devices comprise an Ethernet segment. This mode enables the device to autodiscover Ethernet Ethernet link aggregation remains a vital technology in modern data center networking. EVPN multihoming is managed at the control plane level using EVPN Type 4 routes and the ES-Import Route-Target extended community, which in Junos is an automatically derived 6-byte value taken from The Juniper Networks campus fabrics EVPN multihoming solution supports a collapsed core architecture. You can deploy campus fabrics on a two-tier network with a collapsed core or a campus-wide system that involves multiple buildings with separate distribution and core layers. Configuring Optional Add-Ins. Starting in Junos OS 17. 7. A protect interface provides the benefit of a backup for the protected primary interface in case of failure.

Apr 21, 2023 · EVPN Multihoming uses a Layer 3 IP-based underlay network and an EVPN-VXLAN overlay network between the collapsed core Juniper switches. This example shows how to configure the Link Aggregation Control Protocol (LACP) on multihomed customer edge (CE) and provider edge (PE) devices in an Ethernet VPN (EVPN) VXLAN active-active multihomed network. This example uses EX Series switches with Mist Access Points. It also shows how to use EVPN multihoming to provide multichassis LAG functionality for Layer 2 top-of-rack switches. To each customer (also called a tenant), the service looks like a full-fledged data center that can expand to 4094 VLANs and all private subnets. 36. Merging these layers into a single switch turns the traditional three-tier hierarchical network into a two-tiered network. We’ll also look at configuring active/active multihoming to the environment. An Ethernet VPN (EVPN) enables you to connect dispersed customer sites using a Layer 2 virtual bridge. As with other types of VPNs, an EVPN consists of customer edge (CE) devices (host, router, or switch) connected to provider edge (PE) routers. euijlmaqyshlnsjhsiuopnaawvruiuroxrvovplvpeujq
