New Software Features
Cisco IOS XR Software Release 4.3.0 is a comprehensive release, enhancing each of the applications where the Cisco ASR 9000 Series is deployed. Residential deployment BNG capability is enhanced with a complete IPv6 feature set. Combined with CGv6 capabilities, this provides an attractive IPv6 migration solution. Data center interconnect technology expands both Layer 2 and Layer 3 operations with the support of PBB VPLS and LISP. Typhoon line cards provide intelligent video monitoring, including metrics based on Media Delivery Index (MDI), and Real-time Transport Protocol (RTP). In addition, Stream Merge enhancements for topology independence provide the most reliable multicast solution in the market. Other significant features include a full Generic Routing Encapsulation (GRE) toolkit, Ethernet Operations, Administration, and Maintenance (OAM) Y.1731 Synthetic Loss Measurement, and Network Virtualization (nV) Satellite portfolio expansion with the Cisco ASR 901 and ASR 903 Routers.

Table 3. New Software Features Supported on Cisco ASR 9000 in Cisco IOS XR Software Release 4.3.0
| Feature |
Description |
| BNG IPv6 support and BNG features |
With the 4.3.0 release, the Cisco ASR 9000 Series supports the complete integrated stack of BNG with IPv6 and dual-stack subscribers. This release also supports grouping of subscribers to provide aggregate quality of service (QoS) to the group, and it completes the BNG Lawful Intercept support with tapping based on RADIUS attributes. |
| Network Virtualization features |
Introduced first in Cisco IOS XR 4.2.1, nV Satellite provides significant operational advantages with zero-touch provisioning, faster time to market, and simplified network design. Cisco IOS XR 4.3.0 brings additional capabilities: new Satellite platform support for Cisco ASR 901 and ASR 903, support for Satellite on Cisco ASR 9001 and ASR 9922, and nV Cluster support for Cisco ASR 9001. |
| Video monitoring (VidMon) features |
Existing integrated video monitoring support on the Cisco ASR 9000 has been enhanced in this release. Cisco IOS XR 4.3.0 provides support for these video monitoring features:
● Real-time Transport Protocol (RTP) VidMon
● Media Deliver Index (MDI) (Moving Picture Expert Ggroup MPEG-2) VidMon
● VidMon on Multiprotocol Label Switching (MPLS) traffic
|
| Multicast features |
Cisco IOS XR 4.3.0 provides comprehensive support for next-generation mobile VPN (mVPN) solutions with these additional capabilities:
● BGP Customer-Multicast (C-MCAST) routing
● Topology-Independent Multicast only Fast ReRoute (MoFRR or Stream Merge)
This release also adds support for Protocol Independent Multicast (PIM) Equal Cost Multiple Path (ECMP) Redirect and Multicast Listener Discovery (MLD) snooping. |
| PBB-VPLS with MIRP Lite |
L2 Data Center Interconnect requires very high MAC and VLAN scale, which PBB 802.1ah technology delivers. In Cisco IOS XR 4.3.0, PBB can be coupled with VPLS on the core side, benefitting from MPLS transport resiliency. Multiple I-service Registration Protocol (MIRP)-Lite function is implemented for MAC withdrawal to help ensure fast convergence. |
| LISP |
LISP allows enterprises and service providers to simplify multihomed routing, facilitate scalable any-to-any WAN connectivity, support data center virtual machine mobility, and reduce operational complexities. LISP is a Cisco innovation that is being promoted as an open standard. In Cisco IOS XR 4.3.0, Cisco ASR 9000 provides the support for PxTR capability, together with Cisco Nexus® 7000, providing a scalable and operationally simplified L3 data center solution. |
| Y.1731 Synthetic Loss Measurement and DMMv1 |
Ethernet OAM becomes increasingly important in service provider networks as a SLA management tool. In this release, Y.1731 Performance Monitoring capabilities are expanded with Synthetic Loss Measurement to allow operators to monitor infrastructure and services frame loss. In addition, Delay Measurement is enhanced with new standard version Delay Measurement Message DMMv1, expanding the number of concurrent sessions on a single VLAN to 4000. |
| L2 VPN enhancements: pseudowire grouping, L2 VPN NSR for T-LDP, and MAC withdrawal |
Release 4.3.0 includes multiple enhancements for L2 VPN: single-segment pseudowire grouping for enhanced convergence, Non-Stop Routing (NSR) support for Targeted-Label Discovery Protocol |
| Integrated Routing Bridging (IRB) and L2 interfaces: IRB QoS, ABFv4, and IPv6 ACL on L2 |
IRB interfaces functionality supports QoS functions, allowing policing and marking for traffic on IRB interfaces. Additional feature support includes ABF for IPv4 and IPv6 ACL on L2 EFP. |
| L3 subinterface and IRB CoPP |
Local Packet Transport Services (LPTS) performs the control-plane protection function on Cisco IOS XR platforms. This release enhancement to LPTS introduces awareness of individual subinterface LPTS rates and allows protection of other subinterfaces on the same physical interface. |
| Generalized Multi-Protocol Label Switching (GMPLS) UNI-C |
GMPLS UNI-C defines a signaling interface between routers and ROADMs. Support introduced in Cisco IOS XR 4.3.0 allows routers to request establishing an end to end lightpath across the optical network. |
| IEEE 1588-2008 enhancements |
IEEE 1588-2008 Precision Time Protocol (PTP) support is added for 40-GE and 100-GE interfaces. Also the implementation is enhanced to provide hybrid mode, ITU-T G.6561.1 Telecom Profile compliance, and doubling of the number of clients supported per line card. Further PTP and Network Time Protocol (NTP) interwork is introduced, which allows PTP to be a source when the Cisco ASR 9000 is acting as NTP primary for NTP clients. |
| GRE feature support |
GRE is a versatile IP tunneling protocol widely deployed in networks. Cisco IOS XR 4.3.0 on the Cisco ASR 9000 provides GRE features that give customers the flexibility to transport various types of traffic over IPv4 GRE tunnels, including MPLS; MPLS Virtual Private Network (VPN); Virtual Private Wire Service (VPWS) and VPLS; IPv6, 6PE, and 6VPE; Multicast Multicast-VPN; Resource Reservation Protocol - Traffic Engineering (RSVP-TE); and Bidirectional Forwarding Detection (BFD) packets. In Cisco IOS XR 4.3.0, the GRE scale has also been increased to support up to 2000 GRE tunnels per system. With the inclusion of the GRE features supported in prior releases, the Cisco ASR 9000 now supports a comprehensive set of GRE features. All the newly introduced GRE features in Cisco IOS XR 4.3.0 are powered by Typhoon line cards. |
