Label Path Control

There are two approaches to label path control:

  •      Independent path control means that LSRs are able to create label bindings and distribute these bindings to their peers independently. This is useful when bindings relate to information distributed by routing protocols, and means that nodes can begin to label switch before the completion of a path.

  •      Ordered path control means label binding only takes place if the node is the egress node for the particular FEC, or has received a label binding for that FEC from its next hop. This approach is used to ensure that a particular traffic class follows a path with a specified set of QoS properties.
