Release Information

Statement introduced in Junos OS Release 8.0.


Ignore the metrics for RSVP label-switched paths (LSPs) in IS-IS traffic engineering shortcut calculations or when you configure LDP over RSVP LSPs.

If you are using RSVP for traffic engineering, you can run LDP simultaneously to eliminate the distribution of external routes in the core. The LSPs established by LDP are tunneled through the LSPs established by RSVP. LDP effectively treats the traffic-engineered LSPs as single hops. Ignoring the metric of RSVP LSPs avoids mutual dependency between IS-IS and RSVP, eliminating the time period when the RSVP metric used for tunneling traffic is not up to date.
