Cisco® ASR 9000 Series Aggregation Services Routers deliver unprecedented scale, service flexibility, and high availability for data centers, cloud networks, and business and residential services transport networks. The routers are powered by Cisco IOS® XR Software, an innovative, self-healing, distributed operating system designed for always-on operation while scaling system capacity into multiple terabits per second (Tbps).
Cisco IOS XR Software Release 4.3.2 expands the existing Cisco ASR 9000 Series portfolio with the introduction of the Cisco ASR 9912 Router. Cisco IOS XR Software Release 4.3.2 also introduces Cisco IOS XRv Route Reflector, our first of many virtualized software platforms. Cisco IOS-XRv is a virtual machine implementation of the Cisco IOS-XR operating system, which provides all the platform-independent capabilities of Cisco IOS-XR, allowing it to be used for control-plane applications such as route reflectors. Cisco IOS-XRv has "limited availability" in Cisco IOS XR Software Release 4.3.2 and will be generally available starting with Release 5.1.1. Please contact the Cisco ASR 9000 Series team for more information on this milestone, which is the first of our virtualized software offerings.
New Hardware Features
Cisco IOS XR Software Release 4.3.2 introduces support for the Cisco ASR 9912 Router. The Cisco ASR 9912 is the newest addition to the Cisco ASR 9000 Series, offering the highest density in a compact 30-RU form factor.
Table 1 lists the new hardware support added in Cisco IOS XR Software Release 4.3.2.

Feature
Description
Cisco ASR 9912 Router
The Cisco ASR 9000 Series product portfolio is extended with the introduction of the Cisco ASR 9912 Router, which delivers the most powerful 10-slot system in a 30-RU form factor.
Cisco IOS XRv Route Reflector
Because virtualization is important to customers, Cisco is introducing our first virtualized software platform, the Cisco IOS XRv Route Reflector. It offers Cisco IOS XR control-plane functionality in a virtual form. Customers can now choose between hardware-based route reflectors and pure software-based route reflectors.
PBB-EVPN is a next-generation Layer 2 VPN (L2VPN) technology with significant advantages, including benefits from load balancing capabilities inherent in Layer 3 forwarding technology, active-active redundancy, multihoming autosensing, and prefix-independent convergence. PBB-EVPN significantly reduces flooding in L2VPN networks by introducing control-plane MAC learning. At the same time, PBB encapsulation helps ensure high scale and customer MAC address space isolation. PBB-EVPN is available in Cisco IOS XR 4.3.2 on Cisco ASR 9000 Series routers.
N:1 Network Address Translation (NAT) feature
Prior to the Cisco IOS XR Software Release 4.3.2, the carrier-grade NAT solution on the Integrated Services Module assigned the private-to-public IP address in a random manner. This feature "hard limits" the process of assigning private IP addresses to public IP addresses, based on a configurable parameter (4, 8, 16, 32, or 64), so only a limited number of private IP addresses get mapped to a given public IP address.
TCP maximum segment size (MSS) adjustment
This feature available on the Typhoon line cards allows interception of TCP packets with SYN bit set.
Non-lawful intercept XR images
Lawful intercept as a separate package
Lawful intercept feature allows VoIP and data traffic going through edge routers to be intercepted to meet the requirements of law enforcement agencies. Lawful intercept feature has been completely excluded from the base image for the Cisco ASR 9000 Series.
Base images without lawful intercept feature is: asr9k-mini-px.vm.
Lawful intercept feature is separated from the base image and built as a separate package.
The lawful intercept package for the Cisco ASR 9000 Series platform is: asr9k-li-px.pie.
Install enhancements
Previously, Cisco IOS-XR install operations on platforms like the Cisco ASR 9000 Series and the Cisco Carrier Routing System were limited to a single flash disk (either disk0 or disk1, once booted, but not both).
This release provides the support to install packet on multiple disks.
