This feature detects whether a given EOS image is MLAG ISSU compatible with the currently running version on a switch.

BFD for static routes enables monitoring of directly connected next hop reachability using a BFD session. This is

This document describes BFD RFC7130 mode on EOS. RFC7130 defines a mechanism to run BFD protocol over port channels with an independent asynchronous BFD session on every port channel member link. With RFC7130 support, the port channel member link will be removed from forwarding if the BFD session state transitions from UP to DOWN on the member link. This is useful for quickly detecting failures where L1 stays connected but the interface is unable to forward traffic.

Connectivity Monitor is an EOS feature that allows users to monitor their network resources from their Arista switches. The resources being monitored may or may not be Arista devices. Connectivity monitoring is unidirectional in nature.

DHCPv6 Prefix Delegation support enables a DHCP relay agent to program routes for addresses assigned by a DHCP server. The assigned prefixes could either be DHCPv6 IA_PD prefix delegation addresses, or DHCPv6 IA_NA global /128 addresses.

This feature allows eAPI to run in multiple non default VRFs on the same physical router. In this way, users can

Hardware Table Capacity Monitoring is a new feature to keep track of the capacity and utilization of various hardware forwarding resources and generate alerts/syslogs when the utilization exceeds a threshold value. Users can keep track of the current usage statistics using a single show command, and also configure thresholds on a per-resource basis, to be notified about any high-utilization upfront, before reaching any resource limits. The Main use-case would be for troubleshooting in overflow situations and avoid overflows altogether by taking corrective actions on high utilization.

This feature adds the capability to import as path access-list from a URL, in release 4.20.1F. The file specified by the URL can contain one or more as-path access-list entries. All the entries that are in the file are added to the as-path access-list being configured. This feature gives the advantage of using one EOS CLI command to configure many as-path access-list entries, instead of adding each one of them line by line in the CLI.
