The primary challenge with using a switching ASIC as a load balancer has been how to deal with changes in the network topology without disrupting existing TCP connections.

Filtered Mirroring allows certain packets to be selected for mirroring, rather than all packets ingressing or egressing a particular port.

BGP Non Stop Forwarding (NSF) aims to minimize the traffic loss when the the following scenarios occur:

Egress traffic-policing can be applied on L3 Ethernet subinterfaces for outbound traffic.

The document describes the support for dedicated and group ingress policing on interfaces without using QoS policy-maps to match on the traffic and apply policing.

This feature provides isolation and allows segregating/dividing the link state database based on interface. 

ITU-T G8275.1 is a PTP profile defined by ITU-T for telecommunication applications. It defines a set of functions from the IEEE 1588 to achieve phase/time synchronization with full timing support from the network (meaning, all of the network devices support PTP).

RSVP-TE, the Resource Reservation Protocol (RSVP) for Traffic Engineering (TE), is used to distribute MPLS labels for steering traffic and reserving bandwidth. The Label Edge Router (LER) feature implements the headend functionality, i.e., RSVP-TE tunnels can originate at an LER which can steer traffic into the tunnel.

IPv4 Unicast Reverse Path Forwarding (uRPF) can help limit malicious IPv4 traffic on a network. uRPF works by

This document describes the OSPFv2 feature that allows the setting of “Down” (DN) bit in type-5 and type-7 LSAs. The DN Bit is a loop prevention mechanism implemented when OSPF is used as CE - PE IGP protocol. Its usage in OSPF is explained by RFC4576. By default, OSPF honors the DN-bit in type-3, type-5 or type-7 LSAs in non-default VRFs.
