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
andadjust-interval
to 150 seconds whenadjust-threshold-overflow-limit
andadjust-threshold-underflow-limit
cross the configured threshold values. In releases before Junos OS Release 21.4R1, theadjust-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.]
