A route-set object is a set of route prefixes and not a set of database route objects. Sets can be built with hierarchical names and can also include direct references to other sets. References can also be made indirectly by using the “mbrs-by-ref:” attribute. For more details see the section on Sets.

Where a route-set is expected (e.g. “members:” attribute of the route-set object), an AS number ASx defines the set of routes that are originated by ASx; and an as-set AS-X defines the set of routes that are originated by the ASes in AS-X. A route p is said to be originated by ASx if there is a route object for p, with ASx as the value of the “origin:” attribute. Description of Attributes Specific to the ROUTE-SET Object

  • “route-set:” – This attribute defines the name of the set which must start with ‘rs-‘. It can be a hierarchical name with components separated by a colon (‘:'). At least one component must be a route-set name. The others can be more set names or AS Numbers. All the set name components of a hierarchical name have to be route-set names. For more details see the section on Sets.
  • “descr:” – A short description related to the object.
  • “members:” – These attributes list the direct members of the set. They can be either address prefixes or ranges, other route-set names, lists of AS Numbers, or as-set names. An address prefix or a route-set name in a members attribute can be optionally followed by a range operator.
  • “mp-members:” – Extends the “members:” attribute to include IPv6 address prefixes.
  • “mbrs-by-ref:” – These attributes can be used in all set objects. They allow indirect population of a set. If this attribute is used, the set also includes objects of the corresponding type (aut-num, route-set or as-set objects for route-set, for example) that are protected by one of these maintainers and whose "member-of:" attributes refer to the name of the set. If the value of a "mbrs-by-ref:" attribute is ‘ANY', any object of the corresponding type referring to the set is a member of the set. If there are no "mbrs-by-ref:" attributes, the set is defined explicitly by the "members:" attributes. For more details see the section 'Set Objects'.
  • “mnt-lower:” – When creating hierarchical sets, more specific object creations can be authorised using the “mnt-lower:”, if present, otherwise the “mnt-by:” mntner objects. For more details see the section 'Set Objects'.
