What I Achieved



  • BGP Peering seemed pretty straight forward at this basic level

  • OSPF into BGP also good


 

Noteworth Though



  • BGP into OSPF seem more of a challenge

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 ve

Break the Network Emulators out of the Cloud




























Cisco IOU and JunoSphere Recently both Cisco and Juniper have announced the availability of online resources to provide hands on training over the internet. They have built software emulators in the cloud that can be accessed remotely for a cost. These solutions are based purely around the certification programs and therefore are pretty rigid in the topology that are provided, not to mention the re-occurring cost. http://www.juniper.net/us/en/company/press-center/press-releases/2011/pr_2011_05_16-03_01.html https://learningnetworkstore.cisco.com/market/prod/listSubCatLearnLab.se.work?TRGT=85&/nxt/rcrs/=2559 Rack Rentals There are training providers such as Internetwork Expert (http://www.ine.com/) and IPexpert (http://www.ipexpert.com/) who provide rack rentals based on their training materials. These guy cannot possibly compete going forward. To keep these sustainable they will need to reduce the overhead of building physical racks, providing power and space for the racks.

VMWARE ESXi 5.0 Command line quickies




























 Hi,   It has been a long time since my last posts, but recently I have been working on my home ESXi lab so I thought I would share.   I switched over to using Apple Mac just over a year ago, so I don't have a windows machine running by default to run the vSphere client software and generally all I want to do is startup VMs and switch off the ESXi server when I am done. I did some searching and found that I could use vmware vim-cmd if I SSHed into the ESXi server. This need to be enabled at the console, then you can use putty or your tool of choice to connect.   Anyway there are several commands the following to me are most useful.    List all Virtual Machines  vim-cmd vmsvc/getallvms     Get a Virtual Machines state (on/off etc)  vim-cmd  vmsvc/power.getstate     Power on a virtual machine   vim-cmd vmsvc/power.on     Combining command to a one liner you can find out the power on state of all Virtual Machines   vim-cmd vmsvc/getallvms && for x in `vim-cmd vmsvc/getallvms|
