Hello I would like to set up several AS with a maximum of 15 nodes and then connect 7 of these ASes. This would take 105 nodes. is it possible to reserve this many nodes in a slice?
Would it be more reasonable to reserve for each AS in a site and then connect them.
We plan to conduct some performance studies of inter-AS and intra-AS communications.
At least in my experience you are not likely to succeed getting a single slice this large in one shot. One of two things is a better approach:
I am not sure (2) is worth the trouble for what you are describing.
I have this artifact notebook that shows how to do (2), but again, for your example I wouldn’t worry about this

Thanks Ilya.
Any jupyter examples that I can use to test option 1?
thanks
I think this example creates multiple slices to test MTU between sites
Hi Ilya,
using your above example, I am able to create multiple slices but how do I setup a gateway communication between those slices?
Thanks
Assuming all your slices have their own instances of FABNetv4 network, simply adding a route pointed at the FABNetv4 gateway to the entire FABNetv4 subnet will let your nodes in different slices talk to each other:
full_subnet = ipaddress.IPv4Network('10.128.0.0/10') node.ip_route_add(subnet=full_subnet, gateway=site_net.get_gateway())
