= Scaling Up: How to Grow the Topology of an Existing Experiment = Instructions for the instructor of the [../Procedure Scaling Up] tutorial to reserve the backbone. 1. Do the same pre-work as the students. [../Procedure/DesignSetup#a2.1Pre-work:Installgeni-lib Prework] 1. Get the request RSpec for the backbone using one of the following options: a. Download [bkbone1.xml] a. Generate the RSpec yourself i. Download [bkbone1.txt] to your local machine. i. Run the `scaleup` tool to generate `bkbone1.xml`: {{{ geni-lib/tools/scaleup/rspec_gen.py -r bkbone1.txt }}} 1. Reserve `bkbone1.xml` using the [http://portal.geni.net GENI Portal] or `stitcher.py`. For the purpose of these instructions we assume these resources are reserved in slice `bkbone1`. 1. When all three nodes in the topology are ready, test connectivity between nodes. a. Login to `web1` and ping `10.100.2.2`. a. Login to `rt2` and ping `10.100.1.1`. 1. Download `lan_options.json` and `lan_option_stitch0.json` 1. Share a VLAN at each of the three sites: {{{ omni -V 3 -a wisconsin-ig poa bkbone1 geni_sharelan --optionsfile lan_options.json omni -V 3 -a illinois-ig poa bkbone1 geni_sharelan --optionsfile lan_options.json omni -V 3 -a stanford-ig poa bkbone1 geni_sharelan --optionsfile lan_options_stitch0.json }}} == Extra Backbone == 1. Download `bkbone2.txt`, create `bkbone2.xml`, and reserve the topology in a different slice (we'll called it `bkbone2`). 1. When all three nodes in the topology are ready, test connectivity between nodes. a. Login to `web1` and ping `10.100.2.2`. a. Login to `rt2` and ping `10.100.1.1`. 1. Share a VLAN at each of the three sites: {{{ omni -V 3 -a gpo-ig poa bkbone2 geni_sharelan --optionsfile lan_options.json omni -V 3 -a nysernet-ig poa bkbone2 geni_sharelan --optionsfile lan_options.json omni -V 3 -a missouri-ig poa bkbone2 geni_sharelan --optionsfile lan_options_stitch0.json }}}
