Junos : request chassis cluster failover redundancy-group
content_copy zoom_out_map
request chassis cluster failover node node-number redundancy-group redundancy-group-number
Description
For chassis cluster configurations,
initiate manual failover in a redundancy group from one node to the
other, which becomes the primary node, and automatically reset the
priority of the group to 255. The failover stays in effect until the
new primary node becomes unavailable, the threshold of the redundancy
group reaches 0, or you use the request chassis cluster failover
reset command.
After a manual failover,
you must use the request chassis cluster failover reset command before initiating another failover.
Options
nodenode-number—Number of the chassis cluster node to which the redundancy group fails over.Range: 0 or 1
redundancy-groupgroup-number—Number of the redundancy group on which to initiate manual failover. Redundancy group 0 is a special group consisting of the two Routing Engines in the chassis cluster.Range: 0 through 255

Juniper : SD-WAN
Software-defined wide-area networking (SD-WAN) is an automated, programmatic approach to managing enterprise network connectivity and circuit costs. It extends software-defined networking (SDN) into an application that businesses can use to quickly create a smart hybrid WAN.
Consisting of business-grade IP VPN, broadband Internet, and wireless services, SD-WAN enables you to cost-efficiently manage applications, particularly in the cloud. Traffic is automatically and dynamically forwarded across the most appropriate and efficient WAN path based on network conditions, application traffic security and quality-of-service (QoS) requirements, and circuit cost. You can set the routing policies.
SD-WAN Benefits
Businesses are rapidly adopting SD-WAN technology because of its comprehensive financial and operational benefits.
- Lowers WAN OpEx, CapEx, and overall total cost of ownership.
- Provides greater business agility and responsiveness to keep pace with IT innovations.
- Supports multiple, secure, high-performance connections, eliminating backhaul penalties imposed by MPLS networks.
- Improves performance by enabling load sharing across connections and adjusting traffic flows based on network conditions.
- Supports the automated provisioning of, and changes to, premium network services such as VPNs, firewalls, security, WAN optimization, and application delivery control.
- Supports zero touch provisioning (ZTP).
- Improves network security by encrypting WAN traffic and segmenting the network to minimize damage if breaches occur.
Problems Addressed by SD-WAN
Managing the WAN traditionally has been one of the most expensive and rigid aspects of running an enterprise network. SD-WAN eases this burden by proactively responding to real-time network conditions. It uses programmable network devices that you can modify remotely and through dynamic best-path routing, both of which improve cost, agility, and performance.
SD-WAN Uses and Functions
SD-WAN software running on CPE (customer premises equipment) monitors the conditions of all public and private-line services and determines how to route each type of application traffic. For instance, the default might be to send voice-over-IP (VoIP) traffic over an MPLS VPN service. However, if the MPLS connection becomes congested, the SD-WAN might switch that traffic over to a broadband Internet or 4G LTE wireless circuit. In this way, the SD-WAN enables automatic load balancing and network congestion management for best performance and least-cost effective routing.

Notes:
-
KB30446 - SRX Junos SRX5K Hardware / Software compatibility matrix.
-
TSB17655 - On SRX5000 series with SRX5k RE-13-20 a software upgrade to Junos release 12.3X48-D80, D85 or D90 may fail the pre-check due to insufficient space available on the compact flash.
-
Junos OS upgrade from 18.4R3 or 18.4R3 based Service Releases directly to 19.4R3 or 19.4R3 based Service Releases is supported for all SRX platforms.
-
Notes for upgrading from Junos 15.1X49 releases to 19.4R3 or 19.4R3 based Service Releases:
-
Junos OS upgrade from 15.1X49 directly to 19.4R3 or 19.4R3 based Service Releases is supported for all SRX platforms (ISSU is not supported). Note: PR1572963 - Junos OS upgrade from 15.1X49 directly to 19.4R3-S2 fails on SRX5400 / SRX5600 / SRX5800.
-
In case you would need to rollback or downgrade from 19.4 to the 15.1X49 release on SRX1500, SRX4100/4200, SRX5k or vSRX, all files on the device may be lost. Hence it is important to backup the relevant files (configuration, license-keys etc) before the upgrade and have console access during the upgrade and during a potential rollback if required.
-
For vSRX the following limitations apply when upgrading from 15.1X49 directly to 19.4R3 or 19.4R3 based Service Releases:
-
The file system mounted on /var usage must be below 14% of capacity.
Check this with
root@vsrx> show system storage | match " /var$"
/dev/vtbd1s1f 2.7G 82M 2.4G 3% /var
Note: The CLI command ‘request system storage cleanup’ may help reach that percentage if needed -
The Junos upgrade image must be placed in the directory /var/host-mnt/var/tmp/
request system software add /var/host-mnt/var/tmp/ -
It is recommended to deploy a new vSRX VM instead of performing a Junos upgrade. That also gives the option to move from vSRX to the newer and more recommended vSRX 3.0.
-
-
ISSU is not supported when upgrading from Junos 15.1X49 to any higher versions.
-
KB34945 - When Junos Space Security Director is used for managing the SRX configuration and the AppFW, IDP or UTM features are used, then when upgrading to Junos 18.2R1 or higher, the SRX configuration needs to be migrated to the new Unified Policies style and Security Director version 19.3 or higher is required.
-
Starting with Junos OS Release 17.3, when you upgrade from Junos OS Release 15.1X49 to Junos OS Release 17.3 or higher, or downgrade from Junos OS Release 17.3 or higher to Junos OS Release 15.1X49, you must update the IPS signature package by downloading and installing the IPS signature package update.

Tune the Data Center Fabric with the Latest Advanced EVPN-VXLAN Features
Simplified interconnect for large scale DC fabric infrastructures with seamless EVPN-VXLAN tunnel stitching
Enabling larger EVPN-VXLAN data center infrastructure can be a scaling challenge, requiring additional tools to fully control the way workloads communicate across fabric pods or DC sites. Starting with Junos OS release 20.3, seamless EVPN-VXLAN stitching offers a method to interconnect pods and sites at their edges that provides improved control and scaling.
The figure below shows a data center with four pods. The left side shows an approach that interconnects pods using a full mesh of leaf-to-leaf VXLAN tunnels. The right side uses EVPN-VXLAN stitching, where the intra-pod tunnels terminate at their local interconnect gateway and then just a few VXLAN tunnels are used to interconnect the pods. In this example, tunnel stitching happens at the spine layer, however it can also be done at the super-spine or border-leaf layer, depending on the DC design.
Seamless EVPN-VXLAN stitching has two main use cases:
Multi-pod DC fabric architectures – the interconnect gateways are placed at the spine layer, unifying scaling between the two pods.
Data center interconnect (DCI) – instead of using an over-the-top (OTT) full mesh between sites, the interconnect gateways create the DCI interconnect VXLAN tunnels, thus reducing the number of tunnels and next-hops.
Seamless EVPN-VXLAN stitching simplifies Layer 2 DCI and multi-pod architectures by providing clear demarcation points between pods and sites, thereby enabling improved flood control. As a result, this solution offers better overall scaling.
Improved virtualization and multitenancy with MAC-VRF
Leveraging and implementing virtualization and multitenancy in the data center can be complex, requiring multiple touch points in the architecture to see the first benefits of virtualization.
A new routing instance type, MAC-VRF, adds more flexibility when enabling new server connectivity within the fabric. And with support for edge-routed bridging (leaf routed) and bridged overlay (routed outside the fabric) architectures, MAC-VRF offers a consistent approach to enabling L2 services.
In the figure below, Tenant 44 (MAC-VRF44) and Tenant 55 (MAC-VRF55) are using dedicated MAC-VRF Layer 2 instances on the leaf devices, enabling them to be fully isolated from each other. In cases where these tenants want to communicate, they can add dedicated EVPN Type-5 Layer 3 instances (not shown) to interconnect. This provides the tenants with a range of options to support both their isolation and collaboration needs.
Overall, the MAC-VRF provides additional capabilities for network virtualization and multitenancy. It also offers better control of VXLAN tunnel distribution as well as VXLAN tunnel distribution and flooding optimizations. Plus, it enables interoperability with other vendors.
Application awareness and traffic steering with filter-based forwarding
Not all traffic is equal. When deploying applications in a data center, some applications require more special treatment than others, whether it’s due to how much we trust their traffic or because of the volume of traffic they generate. When these applications are located within the same subnet it can be challenging to provide differentiation. Something is needed to identify and separate each application’s traffic.
Filter-based forwarding (FBF) can help. FBF may not be new, but applying it to edge-routed bridging architectures injects more intelligence into the DC fabric. FBF on QFX5120 leaf nodes enables the operator to forward each application’s traffic as they wish. This makes it possible to enable app steering during a specific time of day, or if a particular app/server begins to show suspicious behavior from a security point of view.
In the figure below, three servers have been deployed in the same IP subnet and by default, their traffic will all be treated the same. However, each server’s traffic has different characteristics: App1 is creating a lot of ‘elephant’ traffic; App2 has low volume but its traffic needs to flow through a specific firewall cluster for more advanced policing; and App3 generates lots of traffic but it’s fully trusted so can flow directly out to the core IP network.
Using filter-based forwarding at the leaf layer adds application awareness of the data center fabric. It also improves load balancing and flow engineering capabilities and offers improved flow isolation.
Improved fabric hardening with enhanced Ethernet loop detection
Modern data center EVPN-VXLAN fabrics have eliminated many of the challenges of traditional 3-tier architectures, such as loop detection. One such challenge is loop detection and prevention. Leaf-spine architectures use all-active link designs and EVPN includes several built-in mechanisms (split horizon, designated forwarder election, MAC mobility tracking) that lower the risk of network instability, compared to legacy Spanning Tree-based infrastructures.
Still, loops can happen when server-to-leaf connections are mis-cabled or misconfigured. Since uptime is a critical metric for any data center, many vendors still recommend using STP. Yes, STP in a modern DC! Fortunately, there’s a better way.
Starting with Junos OS release 20.4, the QFX5120 supports connectivity fault management (CFM) into the DC fabric. Based on the IEEE 802.1ag standard, CFM’s heartbeat mechanism provides enhanced Ethernet loop detection over legacy options like xSTP and BGP. But that’s not all. Through information-sharing within the QFX platform, EVPN can provide information to CFM TLVs like node name, port name and ESI information to help identify the source of the problem.
In the figure below, Server 2 is connected to leaf devices L2 and L4. Both leaf devices are using the same trunk-level VLAN ID. however they have accidentally been configured to use different ESI values. This could create an Ethernet loop. But thanks to CFM heartbeats, the loop has been blocked. Plus, because CFM TLV extensions include details about the problem, the origin of the loop can be identified.
This solution represents a more elegant approach for loop detection within an EVPN-VXLAN fabric, truly eliminating the need for legacy loop detection solutions like xSTP. It also reduces loop detection times and enhances visibility into the cause of the issue, thereby reducing time to resolution.

What is a Fabric, Anyway?
If someone could arrange a competition between different physical network topologies, the spine-and-leaf fabric would reign as the undisputed champion in many ways. What is different about the spine-and-leaf that would declare this type of network topology “the champion?”
The spine-and-leaf is a special kind of network, called a fabric, with some interesting mathematical properties. One of the most interesting, from a design perspective, is that fabrics are regular, which means they are built out of what some may call “micro-modules”— clearly repeatable sections of the network topology. These repeating sections of the network topology are not directly related to traditional modules built around creating failure and security domains, but they still enable some interesting properties related to the design and management of a data center network.
Many five-stage fabric designs easily lend themselves to breaking the network up into fabs and pods, as shown in the illustration below. Any fab or pod can be replaced without impacting the overall fabric design much like an access layer module in a traditional three-layer hierarchical design.
The repeatability of these modules enables automation, just as any other modular network design does. New pods can be added to the fabric and measured while the load is slowly moved onto them to ensure they are operating correctly—all while the fabric is in production. This is called a canary and allows the operator to add or replace network elements at the pod or fab level while controlling risk.
Because pods and fabs can be replaced in this way, they can also be managed in generations, or a repeatable set of hardware, software, configurations and tools. By controlling the number of generations within the fabric, the operator can directly control one of the many elements of network complexity—the variability of configurations.
The spine-and-leaf is also a universal topology, which means it can optimally support just about every kind of traffic flow on a single physical topology. This enables several types of applications, including applications with extremely hard performance requirements, to run efficiently across a spine-and-leaf fabric.
While the spine-and-leaf is a fascinating kind of network topology, many network engineers are still unaware of (or not fully aware of) the many interesting aspects of this network design, its origin and its properties.
