The L2 EVPN MPLS feature is available when configuring BGP in the multi-agent routing protocol model. Ethernet VPN (EVPN) is an extension of the BGP protocol introducing a new address family: L2VPN (address family number 25) / EVPN (subsequent address family number 70). It is used to exchange overlay MAC and IP address reachability information between BGP peers.

EOS-4.24.0 adds support for hardware-accelerated sFlow on R3 systems. Without hardware acceleration, all sFlow processing is done in software, which means performance is heavily dependent on the capabilities of the host CPU. Aggressive sampling rates also decrease the amount of processing time available for other EOS applications.

If a network device uses deep packet inspection for load balancing, RFC6790 recommends deployments to use entropy label in LDP to improve load balancing in MPLS networks by providing sufficient entropy in the label stack itself.

The postcard telemetry (GreenT - GRE Encapsulated Telemetry) feature is used to gather per flow telemetry information like path and per hop latency. For network monitoring and troubleshooting flow related issues, it is desirable to know the path, latency and congestion information for flows at different times.

The`ptp forward-v1` command configures the switch to forward Precision Time Protocol version 1 packets as regular multicast traffic. By default, when PTP is enabled and PTPv1 packets are received on the PTP enabled interfaces, these packets are trapped by the CPU, logged and discarded. The feature is already supported on various Arista platforms, this article highlights added support on the 7280R/7280R2/7020R/7500R/7500R2 platforms in EOS 4.26.0F and on the 7280R3/7500R3/7800R3/7289 platforms in EOS 4.29.0F. It highlights some differences in support for 7280/7500/7800 R/R2 platforms versus 7280/7500/7800 R3 platforms.
