Cisco ASR 9000 IOS XR 64-Bit 3DES Software | Routing, Enterprise — XR-A9K-X64K9-25.3

Maintain secure routing operations on Cisco ASR 9000 platforms with 64-bit IOS XR software and 3DES support. This software is intended for teams that need dependable control-plane software aligned to service-provider and large enterprise edge requirements. Built for the ASR 9000 family, IOS XR provides the operational model Cisco network teams expect for high-scale routing environments: structured configuration, predictable behavior, and support for long-running infrastructure lifecycles. The 64-bit architecture is suited to demanding routing workloads where memory headroom and platform longevity matter. 3DES support addresses environments that still require compatibility with established security policies and legacy encrypted workflows. For organizations maintaining critical routing infrastructure, this software helps preserve continuity without forcing a disruptive platform change. Choose this software when the priority is keeping an existing ASR 9000 deployment secure, supportable, and aligned with Cisco’s routing software stack. It is a practical fit for teams standardizing on IOS XR and protecting the value of installed network hardware. Ideal For Secure an existing Cisco ASR 9000 routing deployment Maintain legacy encrypted routing workflows in service-provider networks Standardize software across ASR 9000 edge infrastructure Support long-term operations on installed Cisco routing hardware Why This Product 1 Built for Cisco ASR 9000 platforms rather than general-purpose routing software 2 Includes 64-bit IOS XR architecture for demanding routing environments 3 Supports 3DES for legacy encrypted workflows 4 Suited to installed infrastructure where software continuity matters
