Cisco ASR IOs Upgrade

m-abooali — Tue, 06 Aug 2019 18:59:10 GMT

Hi folks,

I have two Cisco ASR 1002 routers. I want to upgrade them to the latest IOS. I have downloaded:Cisco ASR 1000 Series RP1 IP BASE
asr1000rp1-ipbasek9.03.02.01.S.151-1.S1.bin

would this IOS supports IP routing like BGP?

also, is the upgrade on ASR routers like any other routers? I have not worked with Cisco ASR routers before.

Please advise,

Best Regards,

Masood

Read the Release Notes very carefully. You can't just go from 3.2.X to 3.16.X unless you upgraded the ROMMON first.

HI,

ok, I am reading through this document. it referring to:

URL-to-consolidated-packag

so, consolidated package is the ios.bin file? or the whole package including web interfaces, etc.!? do I need to upgrade RP ( route processor) too? what I am reading is somehow different from all the upgrades I have performed on Cisco routers and switches, just normal IOS upgrades.

I will read through this document making sure I understand what it says but some info on how this IOS is different from other normal IOS s would be very helpful please.

Please advise,

Best Regards,

Masood

1. Copy the IOS into the bootflash:;
2. Check and compare the MD5 hash value of the IOS in the bootflash:;
3. Change the boot variable statement instructing the router to boot the new IOS in the bootflash:;
4. Ensure the config-registry value is 0x2102;
5. Save the config; and
6. Reboot the router.

Thank you. I has not used ISSU before and I was wondering if ARS1002 was different from upgrading normal routers. this answers my question. thanks again. ASr 1002 doesn't support ISSU.
