EOS is now based on AlmaLinux 9. The document outlines the EOS image base operating system (OS) transition from CentOS 7 to AlmaLinux 9. With CentOS 7 reaching its end of life (EOL) in June 2024 and the impending cessation of active support for CentOS Stream 8 in May 2024, It was decided to migrate directly to a RHEL 9 compatible base for EOS skipping RHEL 8/CentOS 8. EOS 4.32.0 is based on AlmaLinux 9 which is binary compatible with RHEL 9.  

Bug Alerts is a service that runs on Arista CloudVisionTM eXchange (CVX) that provides customers with information on

In an MLAG setup, periodic TCP/UDP heartbeats are sent over peer link to ensure IP connectivity between peers. Prior

MapReduce Tracer is an existing feature that monitors MapReduce nodes that are directly connected to Arista

Segment Routing provides mechanism to define end-to-end paths within a topology by encoding paths as sequences of sub-paths or instructions. These sub-paths or instructions are referred to as “segments”. IS-IS Segment Routing (henceforth referred to as IS-IS SR) provides means to advertise such segments through IS-IS protocol.

E-Tree is an L2 EVPN service (defined in RFC8317) in which each attachment circuit (AC) is assigned the role of Root or Leaf. Root ACs can communicate with leaf ACs and other root ACs. Leaf ACs can only communicate with root ACs. Leaf AC to leaf AC traffic is blocked. In this implementation, ACs are configured at the VLAN level, and the forwarding rules are enforced using a combination of local configuration of leaf VLANs (for local hosts), and asymmetric route targets (for remote hosts).

EOS 4.17.0F adds support for IPv4 address family in OSPFv3 (multiple address family support) based on RFC5838.

EOS 4.17.0F adds support for BFD in OSPFv3. BFD provides a faster convergence in scaled deployments where using

This feature enables dataplane forwarding of IPv4 traffic on interfaces that are not IPv4 address enabled, but only

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

Currently, the 'maximum routes' knob allows one to set an upper bound on the number of routes that can be received from a

This feature provides the ability to track the reason why a BGP path is excluded from the BGP best path selection

IS IS adjacency uptime describes the uptime or downtime of neighbors since the last state change.

This feature enables an Arista switch to run the IS IS routing protocol over a tunnel interface to another IS IS
