Description

Created a sliver named "EG-CT-3" with 1 VM@GPO and 1VM@FIU. Request was submitted to ExoSM without any problem and the sliver is ready, as shown by sliverstatus:

    }
  ]
}

Once logged in, both hosts have the requested IP address, but attempts to ping the remote fail in both directions with "Destination Host Unreachable".

Attaching RSpec.

This functionality is not available. NLR does not give us n2 vlans to connect any rack to any rack...

comment:3 Changed 6 years ago by lnevers@bbn.com

I had not realized that I would not be able to connect the FIU rack to GPO. As part of Confirmation testing, each new site is connected to GPO, but I can modify the FIU test case EG-CT-3 to connect FIU and RENCI to complete the test.

Some feedback about documentation:

Tim pointed me to the page https://wiki.exogeni.net/doku.php?id=private:configuration:network:start in the section "Data Plane" for a list of VLAN assigned for Point-to-point connections. As an experimenter, I would not have easily found this information and then mapped it to the sites I was trying to use. The "Description" in the table should be expanded to add the ExoGENI site names connected by the VLANs (i.e GPO to RENCI).

The page documenting available point-to-point connections is "private" and would not be available to experimenters. Maybe a list of supported connections between racks should be in the public area for experimenters to reference.

The reality is that we will make it possible to do rack-to-rack connections in the next month or so. We do not consider the current situation permanent.

Will complete EG-CT-3 test when the GPO to FIU rack-to-rack connections are available. Test is in "Blocked" state.

Summary: Unable to ping from GPO VM to FIU VM for confirmation test EG-CT-3rack-to-rack connections from GPO to new sites are not possible for confirmation tests - EG-CT-3

New Site Confirmation test EG-CT-3 cannot be completed from GPO to Houston, because VLAN are not available to allow it. As is with FIU, this test will be completed when the connections are in place.

According to Ilya, this restriction should no longer be the case.

But I still cannot exchange traffic between GPO and UFL VMs. Also found cannot exchange traffic between GPO and FIU VMs. Problem is being investigated.

There are currently 3 sites that are blocked with the issue in ticket, once the investigation is completed the confirmation test EG-CT-3 needs to be executed for FIU, UFL and UH.

Resolution: fixed
Status: newclosed

This ticket seems to have been addressed. I was able to connect the GPO rack to each of the remotes FIU, UFL and UH and successfully exchange traffic between GPO and those sites.

Issue is resolved, closing ticket.
