Install via the Cisco Prime Infrastructure or CLI by transferring the .pkg file to the router’s bootdisk, then use install add and install activate commands under admin mode.
Use Cisco’s ISSU (In Service Software Upgrade) feature to perform a hitless upgrade by staging the new package and activating it without disrupting traffic.
You need a supported ASR 9000 platform with at least dual-redundant Route Switch Processors (RSPs), sufficient DRAM, flash storage and compatible line cards for full functionality.
It delivers five-nines availability with stateful redundancy, nonstop forwarding, hitless ISSU, bidirectional forwarding detection and nonstop control plane switchover.
You’ll see line-rate forwarding at scale with granular QoS, deep buffering and optimized hardware pipelines delivering up to 2.4 Tbps per chassis.
The software integrates control-plane policing, MACsec on supported line cards, BGP TTL security, SSHv2, secure SNMPv3, RPKI validation and SDN southbound API authentication.
Under the mpls traffic-eng hierarchy, define TE tunnels, associate explicit paths and bandwidth constraints, then enable RSVP on interfaces to establish TE LSPs.
Maintenance is managed via Cisco Smart Net Total Care for 24/7 technical support, software updates, security patches and access to field-notice advisories.
Use show install summary, show version and show mpls interfaces to confirm active packages, validated feature sets and operational MPLS links.
The product is covered by Cisco’s limited lifetime hardware warranty and offers optional SLAs up to 24/7 support with four-hour onsite response under Smart Net Total Care.
You can order A9K-04.00 through Cisco’s authorized distributors or your Cisco account team, specifying the part number and desired licensing term.
