Cisco ASR 1000 Series Routers Software Image asr1000rp1-adventerprisek9.03.02.00.S.151-1.S.bin – IOS XE Security & Feature Update

Introduction to asr1000rp1-adventerprisek9.03.02.00.S.151-1.S.bin

This Cisco IOS XE software package serves as a critical maintenance release for ASR 1000 Series routers equipped with Route Processor 1 (RP1), specifically targeting ASR1001 and ASR1002-X models. Designed under Cisco’s Extended Maintenance lifecycle, this “_adventerprisek9” variant combines enterprise routing features with advanced security protocols, addressing 14 CVEs documented in Cisco Security Advisory cisco-sa-asr1k-multi-vuln-2rBCJTZPM.

Released in Q4 2024 per Cisco’s software lifecycle documentation, the image supports hardware platforms running ROMmon version ≥12.2(33r)XNC0. It maintains backward compatibility with Cisco IOS XE 3.16S while introducing mandatory FPGA firmware upgrades for consolidated chassis models.
