Software Features Introduced in Cisco IOS XR Software Release 6.2.1
Virtual Private LAN Services
Virtual Private LAN Services (VPLS) is a multipoint Layer 2 VPN technology that connects two or more customer devices using bridging techniques. In this release Virtual Private LAN Services (VPLS) is based on manual configuration of PWs between VFIs provision on the MPLS PE routers. VPLS enables geographically separate LAN segments to be interconnected as a single bridged domain over a packet switched network such as IP, MPLS, or a hybrid of both. Cisco NCS 5000 Series Router builds a point-to-point connection to interconnect two peering customer sites.
A bridge domain, which is the building block for multipoint bridging, is present on each of the PE routers. The access connections to the bridge domain on a PE router are called attachment circuits. The attachment circuits can be a set of physical ports, or both that are connected to the bridge at each PE device in the network.
Disabling Atomic ACL Operations
Cisco NCS 5000 Series Routers supports the Atomic ACL Disable feature for modifications of ACLs. Up until now, the new or modified ACEs were added to the ACL table prior to the removal of the outdated ACEs. Hence, the outdated ACEs consumed hardware resources that were needed for the new ACEs. Therefore, by using a new global configuration option,atomic-disable, the outdated ACEs are removed before adding any new ACEs in the ACL table. The user also has the option of configuring to permit or deny all traffic during the ACL modification.
For more information, see the IP Addresses and Services Configuration Guide for Cisco NCS 5000 Series Routers and the IP Addresses and Services Command Reference for Cisco NCS 5000 Series Routers.
ZTP IPv6 Support on Data Port
Zero touch provisioning (ZTP) allows to provision the routers in your network automatically. However, ZTP on data port was supported only through IPv4 in the previous releases. From this release onwards, ZTP on data port through IPv6 is also supported. For more information on ZTP, see System Setup and Software Installation Guide for Cisco NCS 5000 Series Routers.
RSVP based MPLS-TE with FRR
MPLS Traffic Engineering (MPLS-TE) provides an efficient way to avoid traffic congestion by steering traffic away from congestion points. To forward traffic, MPLS-TE creates unidirectional tunnels from sources to destinations as label switched paths (LSPs).To set up LSPs, Resource Reservation Protocol (RSVP) is used in MPLS-TE to reserve the required resources. Traffic can be steered over MPLS-TE transport using static routes and auto-route announce in interior gateway protocols (IGPs). L2/L3 VPN support over MPLS-TE transport is not available in this release.
MPLS-TE Fast Re-Routing (FRR) handles link or node failures by re-directing traffic to a pre-configured backup path when the primary path fails. MPLS-TE FRR is supported on head end and mid point nodes.
For more information about configuring RSVP for MPLS-TE and FRR, see MPLS Configuration Guide for Cisco NCS5000 Series Routers.
BPDU Guard
Note |
MSTP functionality is not supported. BPDU guard feature error-disables the port on receiving BPDU packets, and the system does not process the BPDU packet further because the feature does not provide any further BPDU packet processing. |
For more information, see the L2VPN and Ethernet Services Configuration Guide for Cisco NCS 5000 Series Routers.
MC-LAG
Multichassis LAG (MC-LAG) enables the user to dual-home a device to two different peer devices, that is, points of attachments, using standard Ethernet Link Aggregation. This provides the user the benefits of active/standby node redundancy, while maintaining single peering. MC-LAG supports two modes; VLAN based active-active and active-standby.
For more information on MC-LAG (active/standby), see the . Interfaces and Hardware Configuration Guide for Cisco NCS 5000 Series Routers, IOS XR Release 6.2.x
For more information on MC-LAG (active/active) pseudo MC-LAG, see the L2VPN Configuration Guide for Cisco NCS 5000 Series Routers, IOS XR Release 6.2.x
Internet Protocol Flow Information Export (IPFIX) 315
Internet Protocol Flow Information Export (IPFIX) is an IETF standard export protocol for sending IP flow information. Cisco NCS 5000 Router supports IPFIX 315 format to export flow information. IPFIX 315 format facilitates sending ethernet frame information of the traffic flow over the network. The process includes sampling, and exporting the traffic flow information. Along with the ethernet frame information, IPFIX 315 format exports information of incoming and outgoing interface of the sampled packet.
Refer the RFC 7270 section 4.18 for information on IPFIX 315 https://tools.ietf.org/html/rfc7270#section-4.18
For more information see System Monitoring Configuration Guide for Cisco NCS 5000 Series Routers.
Using Cisco Yang Models with Puppet
Cisco IOS XR supports the use of Cisco yang models with Puppet. You can install the Puppet Agent within a third-party LXC on IOS XR and enable it to interact with the gRPC and Netconf servers installed natively within the XR LXC. The Puppet Agent uses gRPC Ruby libraries to send and receive Yang data in JSON format. The Puppet Agent interacts with the Netconf server to send and receive Yang data in XML format.
For more information, see the Application Hosting Configuration Guide for Cisco NCS 5000 Series Routers.
Pseudowire Redundancy
Pseudowire Redundancy feature allows you to configure a backup pseudowire in case the primary pseudowire fails. When the primary pseudowire fails, the PE router can switch to the backup pseudowire. You can elect to have the primary pseudowire resume operation after it becomes functional.
For more information on this feature, see the Configure Point-to-Point Layer 2 Services chapter in the L2VPN and Ethernet Services Configuration Guide for Cisco NCS 5000 Series Routers, IOS XR Release 6.2.x.
Software Feature Enhancements in Cisco IOS XR Software Release 6.2.1
Enhancements to Data models - Faster Programmatic and Standards-based Configuration
Data models are a programmatic and standards-based way of configuring and collecting operational data of a network device, replacing the process of manual configuration.
-
Additional open-config models. For the list of all open-config models, see https://github.com/openconfig/public/tree/master/release/models.
-
Additional Cisco-specific and native models. For a list of all Cisco-specific models, see https://github.com/YangModels/yang/tree/master/vendor/cisco/xr/.
To get started with using data models, see the Obtain Data Models section in Programmability Configuration Guide for Cisco NCS 5000 Series Routers.
Security Enhancements
This release addresses following Cisco Product Security Incident Response Team (PSIRT) caveats:
SyncE
Frequency or timing synchronization is the ability to distribute precision frequency around a network. In this context, timing refers to precision frequency, not an accurate time of day. Precision frequency is required in next generation networks for applications such as circuit emulation. To achieve compliance to ITU specifications for TDM, differential method circuit emulation must be used, which requires a known, common precision frequency reference at each end of the emulated circuit.
The incumbent example of frequency synchronization is provided by SDH and SONET equipment. This is used in conjunction with an external timing technology (such as Cesium oscillators or GPS) to provide synchronization of precision timing across the network. As, increasingly, SDH and SONET equipment is replaced by Ethernet equipment this frequency synchronization ability is required over Ethernet ports. Synchronous Ethernet (SyncE) provides the Ethernet physical layer network level frequency distribution of known common precision frequency references.
SyncE support is available for NCS 5001 and NCS 5002. SyncE support is not available on NCS 5011.
For more information, see System Management Configuration Guide for NCS 5000 Series Routers chapter Configuring Frequency Synchronization.
Hardware Features Introduced in Release 6.2.1
In this release, the Cisco NCS 5011 system extends 4x25G breakout support for Copper Optics. PID for Copper Optic is QSFP-4SFP25G-CU3M.
For more information on NCS 5011 router, see Hardware Installation Guide for Cisco NCS 5000 Series Routers.
For information on the optics supported and other specifications, refer the NCS 5011 Data Sheet.

virtual-macaddr-range —This command allows you to configure virtual MAC address settings from the prompt, which was supported in Classic Cisco IOS XR Software. This command does not auto-run, and hence it does not impact the system functionality. If the virtual-macaddr-range is overwritten in the shelf manager component, the new mac addresses will be allocated, and the Cisco IOS XR side link bundles and interfaces are reconfigured. This example shows how to configure the virtual MAC address range in the sysadmin-vm mode.

config sdr <sdr-name> lead_down_delta —This command allows you to configure your own lead_down_delta value. The sdr_mgr component uses the lead_down_delta value to determine whether it is a lead_down event. If the Cisco IOS XR VMs on the two RPs go down one by one with in the lead_down_delta seconds, then it is considered as a lead_down event and the sdr_mgr notifies the clients about this event. If the lead_down_delta value is not configured, then sdr_mgr uses the default value.
