GPO OpenGENI Stitching issues

NOTE: writing as "GPO" ticket, but will move to "OPENGENI" components as soon as it is created.

This ticket captures an issue which has been worked on for the past week.


Initially, the GPO OG rack had no stitching configured. Once configured, and requested that Xi add to the SCS, it was pointed out that the stitching advertisement was incorrect.

Stitching advertisement was updated to introduce the items requested by Xi, along with other naming changes to reflect the hardware in the rack.

After the site was added to SCS, it was possible to create a stitched sliver from GPO OG to Clemson OG, but no traffic can be exchanged. According to the Internet2 Router Proxy, traffic from Clemson makes it to the New York router but is never delivered to the GPO rack host. Traffic from the GPO OG rack is never delivered to the New York router.

Current status:

Waiting for GRAM team to investigate traffic handling at GPO OG switch.

Capturing status update:

According to Stephen the traffic is leaving the GRAM rack and is not forwarded by the site switch poblano. Ali is investigating.

Problem was resolved. It was due to missing VLANs at NoX. Closing ticket.
