Automated config loader

I have recently began the journey again after a three month standstill. Since it was taking a lot of time to shift around the configs, I decided to try to automate as much as possible, so I created a small script:

for (( i=$routerstart, k=$portstart; i<=$routerend, k<=$portend; i++, k++ )) ; do
echo R$i status;
(printf "\n"; echo "enable"; echo "configure replace bootflash:/INE/$DIRECTORY/R$i.txt force ignorecase"; sleep 1; echo "quit" ) | telnet $k | grep -i R$i;

Which really does the job. I have uploaded all config file to routers and this script just uses configure replace pointing to the right directory and txt file.

Pretty neat, since it only takes me 10 seconds to load the configs on all routers.

Please keep in mind that I am using telnet to the port mapped to the serial console of the router. So no matter what config is applied, I should always have access to change it.

I also needed to add some config lines for all config files:


#sed -i '6i version 15.4 \nplatform console serial\nlicense boot level premium' INE-config-files/*/*/*/*.txt


Lab resources

Hi everyone,

My personal lab is made up by:

  • 4x 3560 running IOS 15.0
  • Dell R610 server with 64Gig of memory.
  • Cisco 2500 Access Server
  • 1 wireless access-point – my rack is wireless 🙂


Usual boot time for 10CSR is 13 minute, so for this reason I highly recommend running ESXi 5.5 datastore on a SSD.
With SSD I was able to boot 10CSR in 4-5 minutes.

As for the technology resources I am using INE training materials:

  • INE R&Sv5 ATC
  • INE R&Sv5Workbook
  • Books, books and more books.


Right now the target date for the LAB itself is December 2015. Let’s see how that goes 🙂
