EVPN MPLS VPWS (RFC 8214) provides the ability to forward customer traffic to / from a given attachment circuit (AC)

Forwarding destination prediction enables visibility into how a packet is forwarded through the switch, allowing you to determine which interfaces a packet would egress out of. Typical use cases include, but are not limited to, determining egress members for Port-Channels and ECMPs. Note that ECMPs and Port-Channels are essentially the same in terms of forwarding destinations.

Forwarding destination prediction enables visibility into how a packet is forwarded through the switch and allows

Traditionally, the OpenConfig gNMI service is based on a dial in model. A client sends a request to the gNMI server and

The LDP pseudowire feature provides support for emulating Ethernet connections over a Multiprotocol Label

Egress Peer Engineering (EPE) using BGP LU enables traffic engineering of the links between Autonomous Systems

Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. GUE provides an extensible header format with optional data. In this release, the ability to encapsulate MPLS over GUE packets of variant 1 header format has been added. 

The TCP MSS clamping feature involves clamping the maximum segment size (MSS) in the TCP header of TCP SYN packets if it exceeds the configured MSS ceiling limit for the interface. Clamping MSS value helps in avoiding IP fragmentation in tunnel scenarios by ensuring that MSS is small enough to accommodate the extra overhead of GRE and tunnel outer IP headers.

[L2 EVPN] and  [Multicast EVPN IRB] solutions allow for the delivery of customer BUM (Broadcast, Unknown unicast and Multicast) traffic in a L2VPN and L3VPNs respectively using multicast in the underlay network.
