EOS 4.23.1F TOI

Enough fabric capacity is needed to sustain line rate traffic of front panel ports of each switch element (FAP).

EOS 4.23.1F added basic MLAG support for 7800R3, 7500R3 and 7280R3 platforms. The MLAG features that are currently

EOS 4.21.3F introduces support for BGP Flowspec, as defined in RFC5575 and RFC7674. The typical use case is to filter or redirect DDoS traffic on edge routers.

In the multi agent routing protocol model, the Bgp agent now supports matching community lists with a logical OR via

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 Adj-Rib-In tables.

This feature adds support for user-configured BGP Nexthop Resolution RIB profiles for various BGP-based services e.g. IP unicast, L3 VPN, EVPN, etc. The feature allows an administrator to customize the next hop resolution semantics of BGP routes with an ordered list, or profile, of resolution RIB domains (i.e., either tunnel or IP domain). This allows EOS to direct specific services over the specified RIB domains, overriding the default behavior.

Support for DHCPv4 (RFC 2131)  and DHCPv6 Server (RFC 8415) was added to EOS-4.22.1 and EOS-4.23.0 respectively. EOS DHCP server leverages ISC Kea as backend. The router with DHCP Server enabled acts as a server that allocates and delivers network addresses with desired configuration parameters to its hosts.

Starting with EOS release 4.22.0F, the EVPN VXLAN L3 Gateway using EVPN IRB supports routing traffic from one IPV6

Global layer 3 Maximum Transfer Unit (MTU) feature provides a CLI command to set the MTU value for all layer 3

gRIBI (gRPC Routing Information Base Interface) defines an interface through which OpenConfig AFT (Abstract Forwarding Table) entries can be injected from an external client to a network element.

This feature adds support for offloading BFD Transmit path to hardware (ASIC) for specific types of BFD sessions.

Hardware counter feature allows enabling counters for features using programmable hardware counter resources. This feature can be used to count the following feature specific counters.

Arista campus switches allow extensive and fine grained hardware based flow tracking and management features. They

The goal of Dynamic Flooding is to allow IS IS to scale to large, dense topologies such as Leaf Spine topologies. In such

This feature adds support for allowing multiple destinations in a single monitor session.

When the MLAG peer link goes down, the secondary peer assumes the primary peer is down/dead, and takes over the primary

MLDv2 Snooping optimizes the transmission of multicast packets in Layer 2 by using Layer 3 information contained in

This feature provides per multicast route ingress packet and byte counters for multicast routed packets.

This feature introduces the support for OSPF routes over GRE tunnels under default as well as non-default VRFs. The feature is disabled by default. 

EOS 4.22.1F added support for multiple OSPFv2 instances to be configured in the default VRF. .

The PHY test pattern CLI can be used to check the quality of the physical layer for an Ethernet interface. This is done by

This article describes the support for specifying User Defined Fields(UDF) in Port ACLs including IPv4, IPv6, and

This command stores and displays a list of failed BGP connection attempts for each peer. This may be particularly

The ‘show interfaces interactions’ command aims to provide users a resource that explains various relationships between ethernet interfaces. It describes interactions in which a configuration on an interface causes another set of interfaces to become inactive or have reduced capabilities.Examples include a primary interface consuming subordinate interfaces to service a four-lane speed or platform restrictions that require four interfaces of a port to operate at the same speed.

SNMP IP address ACL support provides the ability to add access lists to limit the source addresses that can be used to

This feature adds three new SNMP traps for MAC move, learn, and age events: aristaMacMove, aristaMacLearn, and

The existing show traffic engineering segment routing policy ... command supports showing the counters per segment

This feature adds support for static inter-VRF routes. This enables configuration of routes to destinations in one ingress VRF with an ability to specify a next-hop in a different egress VRF through a static configuration.

EOS 4.23.1F introduces the ability to configure the color extended community in route map set clauses and in an
