This feature when configured enables users to rewrite the DSCP of the GUE encapsulated header on IP-over-UDP tunnels while preserving the TOS value of the inner IP ( IPv4 / IPv6 ) payload. Starting from software version 4.34.1F, the CLI configuration to enable or disable DSCP preserve globally on the egress interface introduces a clear distinction in the behavior of GUE encapsulation on the core facing interface of the IP-over-UDP tunnels.

Arista access points (APs) support the integration of SESimagotag’s Electronic Shelf Labels (ESLs), which dynamically display prices and offers in retail environments. The SES-Imagotag Retail IoT Connector (USB dongle) connects automatically to the ESLs through a proprietary protocol based on the IEEE 802.15.4 standard. This dongle plugs into the USB port of Arista APs and is managed by SESimagotag’s Serial Communication Daemon (SCD). The SCD ensures seamless AP and USB dongle connectivity to VusionCloud.

The internet exit feature enables hosts attached to a VRF in an edge router to reach prefixes that may be reachable over the internet. Since the addresses assigned within a VRF may be non-routable private addresses which cannot be directly used when going to the Internet, the NAT feature is used as a part of the Internet exit solution to provide internet connectivity.

IPv6 multicast routing protocols are used to distribute IPv6 datagrams to one or more recipients. IPv6 PIM builds and maintains multicast routing using reverse path forwarding (RPF) based on the unicast routing table. IPv6 PIM is protocol-independent and can use routing tables consisting of OSPFv3, IPv6 BGP or static routes, for RPF lookup. MLD is used to discover multicast hosts and maintain group membership on a directly attached link.

With this feature, Arista 7050 and 7050X series of switches can now decapsulate IP in IP tunneled packets. When IP in IP decapsulation is configured, incoming packets with an outer IP header having IpProto=4 (IP in IP) and IpDest matching the one configured will be decapsulated, meaning that the outer IP header will be removed from the packet and all subsequent forwarding decisions will be based on the inner IP header.

When the next hop of an IP route (hereafter referred to as the dependent route) resolves over another IP route (hereafter referred to as the resolving route), the adjacency information of the resolving route’s FEC is typically duplicated into the dependent route’s FEC. With this feature, we prevent the duplication of the adjacency information. Instead, the dependent route’s FEC points to the resolving route’s FEC, forming a hierarchical FEC for the dependent route.

The RCF function is matched against winning routes in the Unicast RIB (seen with 'show rib route …').

IS-IS flexible algorithm (FlexAlgo) provides a lightweight, simplified mechanism for performing basic traffic engineering functions within a single IS-IS area. FlexAlgo requires the cooperation of all nodes within the IS-IS area but does not require an external controller. Paths are computed by each node within the area, resulting in an MPLS switched forwarding path to nodes that are advertising a node Segment Identifier (SID) for the algorithm. The results of the path computation are placed in the colored tunnel RIB or system tunnel RIB, which simplifies route resolution.
