Release Information

Statement introduced before JUNOS Release 7.4.

Description

Amount of time MPLS retains RSVP PathErr messages and considers them for CSPF computations. The more time you configure, the more time a source node (ingress of the RSVP LSPs) can have to learn about the failures of its LSP by monitoring PathErr messages transmitted from downstream nodes.

Information from the PathErr messages is incorporated into subsequent LSP computations, which can improve the accuracy and speed of LSP setup. Some PathErr messages are also used to update traffic engineering database (TED) bandwidth information, reducing inconsistencies between the database and the network.

Options

seconds—Amount of time MPLS retains RSVP PathErr messages and considers them for CSPF computations.

Usage Guidelines

See Improving TED Accuracy with RSVP PathErr Messages.
