  • Support for optimizing auto-bandwidth adjustments for MPLS LSPs (QFX10008)—Starting in Junos OS Release 21.4R1, you can configure faster auto-bandwidth adjustment for MPLS LSPs under overflow or underflow conditions. This feature decreases the minimum allowed value of adjust-threshold-overflow-limit and adjust-interval to 150 seconds when adjust-threshold-overflow-limit and adjust-threshold-underflow-limit cross the configured threshold values. In releases before Junos OS Release 21.4R1, the adjust-interval value is 300 seconds under overflow or underflow conditions.

    You can configure a faster in-place LSP bandwidth update that avoids signaling of a new LSP instance as part of make-before-break. To configure, include the in-place-lsp-bandwidth-update configuration statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level.

    You can also configure RSVP interfaces to support subscription percentage per priority. To configure, include the subscription priority priority percent value configuration statement at the [edit protocols rsvp interface interface-name] hierarchy level.

    [See Configuring Optimized Auto-bandwidth Adjustments for MPLS LSPs.]
