Protect the routing layer that carries your most critical traffic with Cisco SNTC-8X5XNBD coverage for IOS XR IP/MPLS core software. Built for teams that cannot afford prolonged uncertainty in the network core, this support offering helps keep escalation paths clear and recovery timelines predictable when issues affect backbone services. For enterprises running carrier-grade or large-scale campus and WAN routing, the value is not just access to support — it is the ability to preserve operational discipline when a fault appears in the control plane, forwarding path, or adjacent infrastructure. 8x5xNBD coverage fits organizations that staff standard business hours while still needing a defined path to resolution and replacement. This service is well suited to environments where routing stability directly affects application availability, inter-site connectivity, and service delivery commitments. It gives procurement and operations teams a support model that is easier to budget, easier to govern, and more defensible than ad hoc break-fix arrangements. For infrastructure leaders, that means fewer surprises and a clearer standard for sustaining the network core.
