This computational viewpoint specification is related to the pre-provisioned route discovery enterprise and information specification. The objective of the community is to identify appropriate routes for setting up, or reserving the route components for (by using other communities), a trail, a tandem connection or a subnetwork connection. It is possible to request conditions that have to be met by the identified route. In addition to proposing routes, information is provided to help in the selection among the candidate route on the basis of a set of properties. In case of protection, the number of routes corresponds to the protection scheme chosen.
