ABSTRACT:
An apparatus for forwarding data in a data communications network having as components nodes and links therebetween is described. The apparatus is arranged to forward data towards a destination on a label switched path and advertise in a label advertisement to nodes in the network in a label advertisement its label for the label switched path and its label for a repair label switched path for use in the event of non availability of a component in the network. The apparatus is further arranged to advertise to a remote node in the network in a label advertisement additional information for deriving repair label switched path information at the remote node.
