Cisco ASR 9000 Basic 4x1Gbps IP/MPLS/L2VPN License | Enterprise Routing — L-SA9K-L2B-4X1G=

Preserve service readiness on Cisco ASR 9000 infrastructure with a foundation license built for 4 x 1 Gbps IP/MPLS and L2VPN activation. This spare entitlement is intended for environments that need a documented replacement path for licensed capacity without delaying restoration work. For network teams managing metro, edge, or aggregation roles, the value is in keeping the platform aligned with the required service profile when a licensed component must be replaced. It supports the operational discipline procurement and infrastructure teams expect: clear entitlement, predictable recovery, and continuity for routed and Layer 2 VPN services. Because this is a Cisco spare license, it fits organizations that standardize on ASR 9000 and need to preserve the original service posture rather than re-architect around a lower-tier option. That makes it a practical choice for maintaining uptime, reducing administrative friction, and protecting the investment already made in the routing platform.
