Cisco ASR 1000 & Cisco 8000 Router Selection Guide

Plan enterprise, internet-edge and service-provider routing from capacity, interfaces, scale, resilience and software requirements.

Cisco ASR and Cisco 8000 platforms address different routing designs and scales. Start with the required role—enterprise edge, WAN aggregation, internet peering, provider edge or core—then map forwarding, route scale, services and port density.

Do not compare chassis names alone. System capacity depends on the chassis, route processor, forwarding components, interface modules, optics, licences and software release.

Which platform should be evaluated?

ASR 1000 Series

Commonly assessed for enterprise and aggregation roles requiring IOS XE, service integration, VPN scale and resilient edge routing.

ASR 1006-X

A modular ASR option. Define route processors, embedded services processors, interface modules, power, airflow and redundancy as a complete chassis BOM.

Cisco 8000 Series

Evaluate for high-capacity service-provider, cloud-scale and modern edge/core designs that fit the intended IOS XR architecture.

Router design requirements

Area	Questions for the BOM
Traffic	Current, peak and forecast throughput with required services
Routing scale	IPv4/IPv6 tables, BGP peers, VRFs and policy complexity
Interfaces	Port speeds, quantities, optics, breakout and cable distances
Services	MPLS, VPN, QoS, NAT, telemetry, encryption and timing
Availability	Redundant processors, fabric, power, links and field spares
Software	IOS XE or IOS XR release, features, subscriptions and support

Migration planning

Capture interface utilisation and peak traffic over a representative period.
Export route, peer, VRF, QoS and service-policy requirements.
Validate every optic and line-card combination against the target platform.
Model failure scenarios and maintenance operations.
Stage software, configurations and rollback procedures.
Include Cisco support and the required replacement service level.

Frequently asked questions

Is ASR 1000 the same as Cisco 8000?

No. They belong to different platform families and software/design contexts. Selection must follow the intended role and complete technical requirements.

What is needed to quote an ASR 1006-X?

Provide throughput, services, interfaces, redundancy, route scale, software and support needs so the chassis and components can be built correctly.

Can existing optics be reused?

Only after validating part numbers, speeds, reach, software support and target port capabilities.
