Description
OESS advertisement rspecs list links twice, once from the perspective of one side of the link and a second time from the perspective of the other side of the link.
For example the link <oess:link urn="urn:publicid:IDN+oess:foam:nddi+link+I2-CLEV-STAR-100GE-07736" /> is shown as follow in the advertisement:
<oess:link a_node="urn:publicid:IDN+oess:foam:nddi+sdn-sw.star.net.internet2.edu" urn="urn:publicid:IDN+oess:foam:nddi+link+I2-CLEV-STAR-100GE-07736" z_node="urn:publicid:IDN+oess:foam:nddi+sdn-sw.star.net.internet2.edu"/> <oess:link a_node="urn:publicid:IDN+oess:foam:nddi+sdn-sw.clev.net.internet2.edu" urn="urn:publicid:IDN+oess:foam:nddi+link+I2-CLEV-STAR-100GE-07736" z_node="urn:publicid:IDN+oess:foam:nddi+sdn-sw.clev.net.internet2.edu"/>
There should only be one link entry.

Again, this is not a bug. All circuit links are simplex, so these link entries are unique, not duplicates.

You are right I was focusing on the link URN and not the a_node/z_node values.

All network graph edges are simplex. The existence of one direction does not guarantee the reverse path.
