® ASR 9000 Series Aggregation Services Router delivers exceptional scale, service flexibility, and high availability into Carrier Ethernet and business-VPN services transport networks. It is powered by Cisco IOS
® XR Software - an innovative, self-healing, distributed operating system designed for always-on operation while scaling system capacity up to 6.4 Tbps. Cisco IOS XR Software Release 4.0.1 provides new software and hardware feature support for the Cisco ASR 9000 Series Router. This release further enhances the place of the Cisco ASR 9000 Series in the IP Next-Generation Network (NGN). The Cisco IP NGN delivers a Carrier Ethernet design for converged, resilient, intelligent, and scalable transport of consumer, business, wholesale, and mobile services. Applications supported within this framework include residential broadband services such as IPTV and video on demand (VoD), Layer 2 and Layer 3 business-VPN services, and next-generation mobile backhaul transport.
New Hardware Features
Cisco IOS XR Software Release 4.0.1 introduces support for several new shared port adapters (SPAs) on the Cisco ASR 9000 Series SPA Interface Processor 700 (SIP-700) as well as tunable optics.

IRB allows you to combine a routed interface with a bridging domain. You can use the routed interface, termed a bridge-group virtual interface (BVI), in conjunction with typical IP routing protocols. Additionally, the ability to assign a BVI to a bridge domain allows for interbridge group routing. The baseline function of the Cisco ASR 9000 IRB is equivalent to the switch-virtual-interface (SVI) feature on Cisco 7600 Series Routers, although there are some platform-specific differences. The following important IRB features are introduced in Cisco IOS XR Software Release 4.0.1:
• IPv4 Unicast and Multicast Forwarding
• IPv4 Virtual Route Forwarding (VRF)
• Internet Group Management Protocol (IGMP) Snooping
• Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP)
• Stateful Switchover (SSO)
The following important IPv6 Multicast features are introduced in Cisco IOS XR Software Release 4.0.1:
• Multicast Listener Discovery Version 1 (MLDv1) and MLD v2
• Static rendezvous point and embedded rendezvous point
ABF provides an alternative to regular routing by providing the ability to forward to a next hop, based on packet content that extends beyond the destination IP address. The following ABF features are introduced in Cisco IOS XR Software Release 4.0.1:
• IPv4 Forwarding
• Recursive next-hop capability
• Support for up to three next hops with fallback capability
GRE can encapsulate a wide variety of protocol packet types inside IP tunnels, creating a virtual point-to-point link to Cisco routers at remote points over an IP internetwork. The following GRE features are supported in Cisco IOS XR Software Release 4.0.1:
• IPv4 Forwarding
• Routing over GRE interface
BFD per member link
BFD packets are sent out on each member link in an 802.3ad bundle to facilitate detection of link loss within the bundle.
Dynamic ECMP improvements
Cisco IOS XR Software Release 4.0.1 increases the IGP and LDP ECMP possible paths to a maximum of 32.
Per-VLAN Spanning Tree Plus (PVST+) access gateway
The solution supports PVST+ as part of an access gateway solution.
Pseudowire Flow-Based Load Balancing
This feature allows for pseudowire traffic to be load balanced using the IPv4 header information contained in the packets traversing the pseudowire.
The following EFP security features are introduced in Cisco IOS XR Software Release 4.0.1 to prevent IP and MAC spoofing:
• DAI IPSG
• MAC security
LDP and IP Fast Reroute (FRR) with per-prefix Loop-Free Alternate (LFA)
Cisco IOS XR Software Release 4.0.1 extends the IP FRR support to include LDP FRR with per prefix LFA.
MPLS Traffic Engineering (MPLS TE) hop limit
Cisco IOS XR Software Release 4.0.1 allows you to limit the maximum number of MPLS TE hops.
Dynamic LAG with up to 64 members per bundle
Cisco IOS XR Software increases the maximum number of member links within a 802.3ad bundle to 64 while providing dynamic load balancing across member links to avoid polarization.
CFM on MC-LAG
Cisco IOS XR Software enables the use of 802.1ag CFM on MC-LAG bundles.
The following MIBs are added to Cisco IOS XR Software Release 4.0.1:
Cisco IOS XR Software Release 4.0.1 introduces the support of performance monitoring on Layer 2 sub-interfaces, including Stats and Threshold for up to 64,000 EFPs.
Cisco IOS XR Software Release 4.0.1 enhances the QoS capabilities on the fixed Ethernet line cards to include the following features:
• Increased maximum Weighted Random Early Detection (WRED) profiles to 128
• Packets per second policer within a class map
• Port-level sub-rate shaping coupled with hierarchical policy assignment on individual EFPs
Cisco IOS XR Software Release 4.0.1 introduces transparent MPLS functions to the Cisco ASR 9000, including the following:
• Downstream on demand for Border Gateway Protocol (BGP) label redistribution
• Pseudowire over labeled BGP (for internal BGP [I-BGP]+Label)
The following traffic-mirroring enhancements are introduced in Cisco IOS XR Software Release 4.0.1:
• Pseudowire transport for mirrored traffic (pseudowire serves as the destination port)
• Access control list (ACL)-based classification of traffic to be mirrored
• Partial packet mirroring
• Traffic mirroring for Layer 3 sub-interface source port
VidMon Trap and Clone
To supplement the VidMon feature set on the Cisco ASR 9000, Cisco IOS XR Software Release 4.0.1 adds the capability to trap video flows and clone them to a local or remote destination for analysis and troubleshooting.
This systemwide license enables even higher Layer 3 scale on the Cisco ASR 9000. It is not required in a system that uses only the high-queue line cards (that is, no medium- or low-queue line cards present) because the scale support is built into high-queue line cards. Activation of the L3-XL profile in a system that uses the medium- or low-queue line cards requires this license. The activation of VRF capability still requires the use of the appropriate per-line-card license (A9K-IVRF-LIC, A9K-AIP-LIC-B, or A9K-AIP-LIC-E).
