Hi Julien, all
Related to path computation yang model, you raised some time ago a request to address the requirement we summarized in issue #65<https://github.com/rvilalta/ietf-te-path-computation/issues/65> of path computation github.
After coordination also with TEAS te-tunnel model authors/contributors we went to the conclusion the current RPC already support the requirement of reporting bidirectional path with asymmetric path
properties.
The path compute RPC request will requests to compute two paths (the forward and the reverse path).
The path request for the reverse path will have an empty "route-object-include-exclude" (to indicate that the reverse path is co-routed with the forward path) and no path constraints (to indicate that the path constraints are the same as the forward path).
The path compute RPC reply will return both computed paths with the path properties of the forward and reverse paths.
With this feedback we consider the issue closed.

Thanks

Italo and Sergio on-behalf of authors/contributors
