Timeout exceeded for FABNETv6 usage

[yoursunny]

I’m trying to use L3 network with IPv6, but found that slice.submit() always times out.
I tried <i>create_l3network_fabnet_ipv6</i> notebook as well as a simple script, and both have the same result.
The slice shows up in Portal but is stuck in <i>Configuring</i> state even after several hours.

The script:

import time
from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager

fablib = fablib_manager()

slice = fablib.new_slice(name=f'demo-{int(time.time())}')
nodeA = slice.add_node(name='A', site='WASH', image='default_ubuntu_22')
intfA = nodeA.add_component(model='NIC_Basic', name='nic').get_interfaces()[0]
slice.add_l3network(name='l3v6', interfaces=[intfA], type='IPv6')
slice.submit()

slice = fablib.get_slice(name=slice.get_name())
nodeA = slice.get_node(name='A')

slice.wait_ssh(progress=True)
print(nodeA.get_ssh_command())

The output:

We are experiencing a heavy load and we are still optimizing the behavior. Your slice should eventually complete, but you may need to be patient.

Yes, the slice(s) eventually became StableOK after more than 4 hours.

I was disappointed to find that FABNETv6 does not allow access to the Internet despite having public addresses, so that I still have to use the (supposedly) slow management network for any Internet access.

Opening up public connectivity from FABNetv[4,6] on demand is a feature that is currently in testing for a small number of projects. We expect general availability of this feature with the Release 1.4.

FABRIC Testbed Release 1.3
