ALPM (Algorithmic Longest Prefix Management) is a scheme in which the route prefix is split and stored across DEFIP

The document captures the default preference value (between and 255) for routes from various supported protocols.

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

Multihoming in EVPN allows a single customer edge (CE) to connect to multiple provider edges (PE or tunnel endpoint).

Filtered Mirroring allows certain packets to be selected for mirroring, rather than all packets ingressing or

EOS supports the ability to match on a single VLAN tag (via encapsulation dot1q vlan 10)  or a VLAN tag pair (via

There are use cases where all broadcast, multicast  and unknown MAC traffic are not needed to be flooded into the

IGP shortcuts enable traffic to get forwarded along traffic engineered paths computed by RSVP using a modified SPF

The  Inband Network Telemetry eXport Data (INT XD) feature is used to gather flow, queue, drop telemetry

IPv4 routes of certain prefix lengths can be optimized for enhanced route scale. The feature is described here. This

The IS IS maximum LSP size feature provides the ability to configure the maximum LSP size that the IS IS protocol will

Media Access Control Security (MACsec) is an industry standard encryption mechanism that protects all traffic

Media Access Control Security (MACsec) is an industry standard encryption mechanism that protects all traffic

MLDv2 Snooping optimizes the transmission of multicast packets in Layer 2 by using Layer 3 information contained in

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.

A mDNS Gateway extends the link local scope of mDNS messages to additional subnets to provide service discovery and

This solution allows delivery of multicast traffic in an IP VRF using multicast in the underlay network. It builds on

This TOI describes a set of enhancements made to the existing Port Security: Protect Mode (PortSec Protect) feature.

Power over Ethernet (PoE) is a way of delivering power and data over the same Ethernet wires. There have been multiple

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.

IS IS adjacency is not formed between devices with different address families configured. For example,  a router
