The default policy behavior is to permit/accept all routes when a BGP neighbor or peer group is configured with a route

BGP Monitoring Protocol (BMP) [1] allows a monitoring station to connect to a router and collect all of the BGP

BGP Monitoring Protocol (BMP) allows a monitoring station to connect to a router and collect all of the BGP announcements received from the router’s BGP peers. The announcements are sent to the station in the form of BMP Route Monitoring messages generated from path information in the router’s BGP internal tables. A BMP speaker may choose to send either Adj-Rib-In routes, or Loc-Rib routes (as defined by RFC9069), or both.

EOS by default selects the prefix for ECMP if the two paths have the same AS PATH length regardless of the ASN values in

The BGP idle restart interval feature allows an idle BGP peer session to automatically restart after a configurable

When a core router has competing advertisements for the same prefix from various PEs, the local edge route should be selected as the best path based on the IGP metric of the resolving routes of those competing advertisements. Without the support mentioned in this TOI, when a BGP route has two or more levels of recursion, the BGP process does not utilize the IGP distance in the route selection process. 

BGP Non Stop Forwarding (NSF) aims to minimize the traffic loss when the the following scenarios occur:

The sub route map configuration simplifies routing policies by sharing common policy across route maps. Common

BGP Prefix Independent Convergence (PIC Edge) refers to fast re-convergence of traffic destined for BGP prefixes on a network event affecting the best path(s) such that the time taken to switch traffic from the active best path(s) to the next best path (i.e. backup path) is independent of the number of prefixes. The above behavior is achieved by pre-programming the best path and alternate backup path in the forwarding agent in steady state. 

The BGP Prefix Independent Convergence (PIC Edge) is an existing feature that was first introduced in EOS 4.15.0F.

The Campus Dashboard provides an overview of your network state. Devices stream telemetry data to CloudVision in real time, giving you immediate and up-to-date insights into your network’s health. The timepicker can be used to view historic data of the network state.

The Campus Fabric studio allows you to set up and configure a complete campus network using Arista’s validated designs. By leveraging zero touch provisioning (ZTP), you can seamlessly onboard EOS devices, define their roles and connections within the fabric, and configure L2 and L3 services across the fabric. 

Deployments utilizing VXLAN, a routing underlay (OSPF or eBGP), and a routing overlay (eBGP) are supported, and you can also define connections to non-EOS devices in the fabric. Additionally, PTP, 802.1X, IP locking, and other network features are supported by the studio.

The Campus Health Dashboard provides an overview of your network state. Devices stream telemetry data to CloudVision in real-time, giving you immediate and up-to-date insights into your network’s health. The timepicker can be used to view historic data of the network state.

This is an addition to the SSL certificate and key management feature added in EOS 4.15.0F.

 With the 12.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces Channel Maps. This chart displays the number of clients and access points (APs) visible to the managed device at a time on a given channel.

With the 12.0 release, you can view the criteria and parameters that influenced a channel change event. The data provides you insights on why the access point (AP) selected a particular channel over another.

With the 14.0 release, CV-CUE brings the ability to create checkpoints to save your current configurations, profiles, and settings. Creating and restoring a checkpoint is possible for all configuration settings available in CV-CUE. You can create a checkpoint for location based configurations, group configurations, or global configurations. For all the configurable settings that are available for a network, you can create a checkpoint to save it. 

Class Based Forwarding (CBF) provides a means for forwarding traffic through selected tunnels based on the traffic class of the incoming packet. Starting 4.32.2F CBF supports forwarding MPLS labeled traffic based on the EXP value in the incoming packet or the internal traffic class (TC) resolved from the parameters of the packet (e.g TC derived from EXP bits combined with port trust mode). Here, EXP bits refer to the Experimental bits in the MPLS header.

In order to use the BST(Binary Search Tree) resources more efficiently for multicast, we are introducing a new CLI

With the 18.0 release, you can perform Client Connectivity Tests (CCT) in a network that has deployed proxy servers.  CCT lets you use the Access Point’s third radio as a client that can connect to another AP you want to test. This gives you the ability to proactively validate network connectivity, the reachability of network services, and the quality of experience for critical applications such as VoIP.  For more information on CCT,

With the 17.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces a redesigned dashboard for viewing client details. The following image shows the new client details dashboard:  Along with client and network details, the client details dashboard also contains multiple data points regarding client connectivity, performance, and application experience. From a single dashboard, you can conduct live troubleshooting, and review past data to identify and troubleshoot past issues, thus resulting in a faster resolution.

With the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces the Client Explorer view. It helps you view the distribution of clients that are connected to Arista devices.

CVA 7 is a full rebuild of the CloudVision Appliance (CVA) software on a new architecture. The new architecture provides a much richer set of management and security primitives. It is fully controllable by REST API, Web based GUI or CLI, all of which expose all features.

Profiles are assigned to user accounts to customize their landing page on CloudVision and present information relevant to them. You can use built-in profiles or create custom ones. Profiles are assigned in Users to user accounts.

Cluster Load Balancing is a feature designed to ensure optimal load balancing of flows used as part of GPU based cluster communication. When this feature is enabled, a TOR router monitors RoCE traffic flowing between the GPU servers and spine uplinks and ensures optimal load balancing in the network.

Common Management Interface Specification (CMIS) defines, starting with revision 4.0, a standard mechanism for managing the firmware of compliant transceivers. This mechanism allows for transceivers’ firmware to be updated without having to remove the transceiver from the switch. Firmware updates may be necessary in a testing or production environment to resolve potential firmware bugs. Some transceivers may also support firmware management operations in a hitless manner (without impacting traffic).
