ABSTRACT:
Methods and apparatus for allowing routers in an autonomous system to implement LDP and RSVP at the same time. RSVP can be used in the network core with LDP being used in network regions surrounding the core. LDP LSPs are tunneled through the RSVP network core using RSVP LSPs and label stacking techniques. During route selection LDP LSPs which use an RSVP LSP tunnel are preferred over alternative LDP LSPs having an equal cost associated with them to create a preference for traffic engineered routes.
