ASR1006 Dual Route Processors Password Recovery - Tip

I recently ran into an issue when trying to perform dual route processors password recovery on a Cisco  ASR1006

Problem


After breaking into rommon mode and using confreg to ignore the startup configuration, during the rest the ASR1006 loaded the startup configuration!!!!!!!!

Solution


So quick and simple, I pulled one of the RP and preformed password recovery running on a single RP. All went according to the Cisco documentation

http://www.cisco.com/en/US/docs/routers/asr1000/install/guide/routers/asr1_hwc.html#wp1045971

 

After the system running on a single RP was recovered and fully booted I waiting for 5 minutes just to be sure; then I inserted the second RP and allowed everything to sync up.

 

All was well again :) phew

 

Note: The system was previously fully functioning with dual RPs; a configuration error was made during Tacacs+ configuration which resulted in lockout.

 

Summary


I hit an issue recovering and ASR with dual RPs, so rather that spending hour researching, I decided very quickly to go for a short cut and only perform password recovery on a single RP then allow the second RP to sync up once the system was backup and running. I am not sure how relevant this process would be with other system with dual RP/Supervisors, but might be work a hack if you run into similar issues. Hope it helps you out.

From IOS to Junos – JNCIA Result - PASS

I done the exam, and I am please to say I passed. So the lab-ing and the two PDFs

JNCIA-Junos_SG_part_1_09-16-2010.pdf
JNCIA-Junos_SG_part_2_09-16-2010.pdf

And a bit of surfing the web were enough. That is not to say everything in the exam was familiar, I did have to think seriously about some questions which puzzled me.
So the next step will be to go for specialist, but because of workload, it's going to take a little longer that 15 Days.

NetGuruSubnetCalc

This is a straightforward no nonsense Subnet Calculator. It does however allow you to pull up the subnet information you have been working on in the iPhone Todays Widget View. This means that the subnet information is just a slide away.
