Cisco IOS XR IP/MPLS Core Software | Carrier Routing, Core Network — XR-A9K-PX-06.02

Maintain the routing foundation of your network with Cisco IOS XR IP/MPLS Core Software. Designed for core infrastructure, this software supports IP/MPLS environments that demand scale, control, and predictable behavior under load. Core routing platforms carry the traffic that cannot fail. IOS XR is built for that role, giving network teams a software foundation for backbone services, service provider transport, and large enterprise cores. It is the kind of platform software chosen when routing policy, service continuity, and operational discipline matter more than feature checklists. For architects and operations teams, the value is in running a core network stack that is purpose-built for high-demand routing environments. For procurement, it represents software tied to a critical infrastructure layer rather than a general-purpose license. That distinction matters when the network supports revenue systems, customer services, or inter-site connectivity at scale. If your environment depends on stable IP/MPLS core behavior, this Cisco software belongs in the shortlist.
