Abstract
In one example, a network device includes a hardware-based processor, and a Resource Reservation Protocol with Traffic Engineering extensions (RSVP-TE) module executing on the hardware-based processor that establishes a plurality of label switched paths (LSPs) having the network device as a common transit network device. The network device presents a plurality of options for selection, which each specify a different algorithm for selecting LSPs to evict from the link. In response to detecting an over-subscription condition on a link along the plurality of LSPs, the RSVP-TE module selects a subset of the plurality of LSPs to evict from the link, and the RSVP-TE module outputs an error message to one or more ingress network devices associated with the selected subset of LSPs without outputting an error message to the ingress network devices associated with those LSPs not selected for eviction.
