Fully automated initial installation
● Bootable ISO: To simplify installation, Cisco IOS XR Software 64-bit on ASR 9000 images are in the form of a bootable ISO that’s installed on the system. The software also supports iPXE, which allows the administrator to boot from TFTP, HTTP, or FTP.
● Auto-provisioning: Auto-provisioning starts at the end of the software’s boot process and serves two functions: static configuration application and script execution. It allows administrators to customize settings easily and automatically, without wasting time on manual configuration.
Visibility for smarter control, simpler monitoring, and faster troubleshooting
● Model Driven interfaces: Prior to Release 6.0, administrators relied on Simple Network Management Protocol (SNMP) and syslog—techniques that are neither scalable nor easily automated. With this latest release of Cisco IOS XR Software, administrators can more easily work together using the internal system database (SysDB) represented by YANG models. SysDB is not a database in a strict sense, but rather a tree-like file system that can provide a common mechanism for management clients to modify or access system information. SysDB stores a variety of types of data, including integers of different sizes, character strings, and externally managed data items.
Linux-based OS: Release 6.1.2 opens up the architecture of Cisco IOS XR Software using a 64-bit Linux-based operating system. (It uses the Wind River 7 distribution, which is compatible with Yocto 1.5 and approved by the Yocto project.) In contrast to the traditional 32-bit QNX OS, Release 6.1.2 can easily integrate applications, configuration-management tools, and autoprovisioning. These attributes make it highly automatable and transparent to monitoring and management tools.
In-Service Software Upgrade (ISSU)
In-Service Software Upgrade: Cisco IOS XR Software 64 bit on ASR 9000 will have new foundation for the In Service Software Upgrade. The virtualized environment to run instances of Cisco IOS XR Software 64 bit will enable the platform to provide capability to orchestra software upgrade process to minimize the disruption of the services in the network without powering down the system to upgrade the Cisco IOS XR Software 64 bit on ASR 9000.
Segmented Multicast Stitching with Inter AS support on Cisco IOS XR Software 64 bit
Segmented Multicast Stitching with Inter AS is now supported on Cisco IOS XR Software 64 bit. The segmented multicast stitching with Inter AS solution makes sure that the ABR and ASBR having an incoming core type is switched to a different or same core type.
MLDP Carrier Supporting Carrier Based MVPN support on Cisco IOS XR Software 64 bit
MLDP Carrier Supporting Carrier Based MVPN is now supported on Cisco IOS XR Software 64 bit. The MLDP carrier-supporting-carrier (CSC) feature enables one MPLS VPN-based service provider to allow other service providers to use a segment of its backbone network.
Multicast VPN, MVPN over GRE and Multicast only Fast Reroute support on IOS XR 64 bit
Multicast VPN (MVPN), MVPN over GRE (MoGRE) and Multicast only Fast Reroute (MoFRR) features are now supported on Cisco IOS XR Software 64 bit.
Global Table Multicast support on Cisco IOS XR Software 64 bit
Layer 3 Global Table Multicast (GTM) is now supported on Cisco IOS XR Software 64 bit. Multicast routing information that is not specific to VPNs is stored in a router's "global table", rather than in a VRF and hence it is known as "Global Table Multicast".
The following Cisco platforms support Cisco IOS XR Software 64 bit on ASR 9000:
● Cisco ASR 9000 Series routers with RSP800 or RP2 (both –SE and –TR) and the latest generation ASR 9000 Linecards, for example, A99-8X100GE-SE/-TR, A9K-8X100GE-SE/-TR, A9K-4X100GE-SE/-TR.
