Cisco 12K Series PRP IOS Service Provider (SKU S12KZ-12.0.33S) is a carrier-grade IOS release for the Cisco 12000 Series routers, delivering advanced routing, MPLS, and service-provider features in a single software package.
Key features include multi-terabit forwarding capacity, full MPLS and VPN support, granular QoS, high-availability mechanisms, and integrated control-plane security.
By leveraging hardware-accelerated packet forwarding, optimized MPLS label switching, and tiered QoS, Cisco 12K Series PRP IOS maximizes throughput and minimizes latency in service-provider environments.
Cisco 12K Series PRP IOS scales to millions of routes, supports thousands of MPLS labels, and delivers up to multi-terabit switching capacity per chassis for growing network demands.
The software supports advanced routing protocols (OSPF, IS-IS, BGP), MPLS, segment routing, IPv4/IPv6 forwarding, multicast (PIM), and VPLS/E-VPN services.
Licensing uses Cisco’s Smart Licensing model, allowing you to register, manage, and allocate feature-based entitlements through your Cisco Smart Account portal.
Yes, you can perform an in-service software upgrade from earlier 12.0S releases or 12.0T images, following Cisco’s documented upgrade paths to minimize disruption.
Security features include control-plane policing (CoPP), ACLs, encrypted BGP sessions, route filtering, and optional integrated IPsec for secure site-to-site tunnels.
It offers redundant route processors, Stateful Switchover (SSO), nonstop forwarding (NSF), and hitless upgrade capabilities to maintain service continuity.
This software supports Cisco 12000 Series chassis—including the 12404, 12406, 12408, 12416, and 12420—with supported line cards and route processors.
Use class-based QoS policies, hierarchical bandwidth allocation, priority queuing, and MPLS EXP marking to guarantee SLAs and traffic differentiation.
Cisco offers SMARTnet Service for 24×7 hardware replacement, software updates, technical support, and access to TAC knowledge base for rapid issue resolution.
Enable MPLS globally, configure LDP or RSVP-TE, assign MPLS to interfaces, and establish VRFs for VPNs using step-by-step commands from Cisco’s configuration guide.
Yes, it supports Cisco’s SD-Access, path computation element (PCE) integration, and programmatic control via NetConf/YANG and Cisco IOS XR REST APIs.
Use built-in SNMP, telemetry streaming, NetFlow, and Cisco Prime or third-party NMS tools to collect real-time performance metrics and fault notifications.
