    v1 v1  
     1Experiment with Junipers connected to pcs/vms using VLAN'ed links
     3This type experiment has two major limitations
     5a) PC/VMs used can only be from the Utah Testbed with its phsyical location being either at the University of Utah or any of the internet2 POP where the Utah Testbed's HP Procurve switch is located.
     6b) Currently this involves manully editing the rspec to add vlantags . This support is not available when using FLACK. So this experiment has to be created using the protogeni Test Scripts
     9(Below stuff in shadownet_stitch.notes)
     12Lets create such an experiment using the rspec below.
     13(insert shadownet_stitch_utah.rspec here)
     15If you look at this rspec, you notice that we request three raw-pc nodes and three virtual devices called emulab-bbg from the Utah Testbed. The emulab-bbg devices are vlan reservations requested for each link utilizing this emulab-bbg device with a pc node.
     17Charles : You may want to put a visual here on how the experiment looks like
     19use the PG script
     21./createsliver -n shadow-demo -m shadownet_stitch_utah.rspec
     24Save the manifest
     26./sliverstatus -n shadow-demo -m until sliverstatus returns a ready state.
     29Once we have a ready state, we now look at the manifest returned and note down all the "vlantag= " returned for each link
     31Now create a copy of the original rspec and comment out all the utah sections and uncomment all shadownet sections.
     32Replace the VlanId attributes in each link with the relevant Vlan Tags and the IP addresses on the each link in the juniper section.
     34Look at the shadownet_stitch.rspec
     36submit this to the shadownet CM
     38./createsliver -n shadow-demo -m shadownet_stitch.rspec
     40Save the manifest
     42./sliverstatus -n shadow-demo -m until sliverstatus returns a ready state.
     46Once the experiment is up and running, we have to setup routing on the routers and the pcs to talk to each other.
     47The set of commands and its output for this example are shown below.
