Stitching request for two links between InstaGENI nodes fails while VLANs are available

Description

Creating this stitched sliver topology always fails:

  • Utah IG if0 <-link1-> GPO IG if0
  • Utah IG if1 <-link2-> GPO IG if1

The create sliver fails at each aggregate always with a link error "vlan tag for link2 not available". The same failure occurs if the sliver is created between PG Utah and IG GPO.

These errors are reported while there are VLANs available for the sliver.

This is no longer an issue. VLANs are allocated as expected.
