The BGP graceful restart mechanism has a limitation that the graceful restart time cannot exceed 4095 seconds per the

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

This feature adds support for BGP peering with multiple peers using the same IP address. The router id of those peers is

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.

This feature allows classification of packets on QoS policy-maps based on the COS/Vlan+COS bits in the 802.1q header of the packet. CoS (Class of Service) corresponds to the Priority code point (PCP) bits in the 802.1q header.

This feature allows classification of packets based on the inner VLAN value along with the VLAN and CoS bits in a double tagged packet.

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

The current behaviour on R series products is to drop all packets marked for drop by the chip Packet Processor in the

The multicast route counters count packets and bytes per group, source and vrf. Every multicast route will be counted when the feature is turned on if there are sufficient hardware counter resources available. 

This article describes the Tap Aggregation MPLS Pop feature. The purpose of this feature is to support tools that do not parse MPLS labels and therefore need the switch to remove (pop) the MPLS header.

As of EOS-4.25.2F some advanced Tap Aggregation features require the hardware forwarding profile to be set. On EOS-4.25.2F these features are MPLS Pop and 802.1br-E/VN Tag Stripping.
