Hierarchy Level


Enable Resource Reservation Protocol (RSVP) signaling.

You must include the rsvp statement in the configuration to enable RSVP on the router.

The primary purpose of RSVP in Junos OS for EX Series switches is to support dynamic signaling within label switched paths (LSPs).


cross-credibility-cspf—Enable path computation across credibility levels. The constraint path computation is run across multi-protocol links and nodes, instead of a credibility-by-credibility basis.

authentication key—Authentication key. Neighboring routers use the password to verify the authenticity of packets sent from this interface or peer interface. It is recommended to use the authentication-key configuration at the [edit protocols rsvp] hierarchy level for the RSVP node-neighbor.

graceful deletion timeout—Specify the time, in seconds, before completing graceful deletion of signaling.

graceful restart—Configure graceful restart on the router. You must configure the graceful-restart statement at the [edit routing-options] hierarchy level to enable graceful restart on the router.

hello acknowledgements—Enable hello messages from nonsession neighbors to be acknowledged with a hello acknowledgment message. Once hello acknowledgments are enabled, the router continues to acknowledge hello messages from any nonsession RSVP neighbors unless the interface itself goes down or the configuration is changed by an administrator.

interface—Enable RSVP on one or more router interfaces.

bandwidth—Enables you to specify the actual available bandwidth.

hello interval—Enable the sending of hello packets on the interface.

link protection—Using link protection, you can configure a network to reroute traffic quickly around broken links.

priority—Configure the setup priority and reservation priority for a bypass LSP.

exclude-srlg—Exclude Shared Risk Link Group (SRLG) links for the secondary path for critical links where it is imperative to keep the secondary and primary label-switched paths completely disjoint from any common SRLG.

hop-limit—Specify the maximum number of routers that an LSP can traverse. Maximum number of hops.

bypass—Enables you to configure specific bandwidth and path constraints for a bypass LSP.

max bypasses—Specify the maximum number of dynamic bypass LSPs permitted for protecting this interface.

no cspf—Disable CSPF computation on all bypass LSPs or on a specific bypass LSP. You need to disable CSPF for link protection to function properly on interarea paths.

optimize-timer—The optimize timer initiates a periodic optimization process that reshuffles data LSPs among bypass LSPs to achieve the most efficient use of network resources.

path—Configure an explicit path (a sequence of strict or loose routes) to control where and how a bypass LSP is established.

update threshold—Adjust the threshold at which a change in bandwidth triggers an interior gateway protocol (IGP) update.

keep multiplier—Indicates the number of messages that can be lost before a particular state is declared stale and must be deleted. The keep multiplier directly affects the lifetime of an RSVP state.

no authentication check—Skip authentication check for received messages.

node hello—Enable node-ID based RSVP hellos globally on all of the RSVP interfaces on the router to allow Juniper Networks routers to interoperate with the equipment of other vendors.

peer interface—Configure the name of the LMP peer device.

no-enhanced-frr-bypass—Enable no-enhanced-frr-bypass to turn off all Fast reroute (FRR) facility protection enhancements, which includes improved LSP scaling and enhanced RSVP message handling, and reduce the default refresh time to 30 seconds.

no-interface-hello—Explicitly disable RSVP interface hellos globally on the router.

no-local-reversion—Disable RSVP local revertive mode as specified in RFC 4090, Fast Reroute Extensions to RSVP-TE for LSP Tunnels.

no-node-hello-on-bypass—Starting with Junos release 16.1, Junos routers send RSVP hello packets over a bypass LSP (when one is present), instead of the IGP next hop. To return to the original behavior specify the no-node-hello-on-bypass option.

no-node-id-subobject—Disable the record route object (RRO) node-ID subobject for compatibility with earlier versions of Junos OS.

pop-and-forward—Specify RSVP pop-and-forward LSP tunnel-specific global parameters.

refresh time—Periodical refresh timer expressed in seconds.

setup-protection—The facility-backup fast reroute mechanism can provide setup protection for LSPs which are in the process of being signaled.

traceoptions—The default RSVP-level trace options are those inherited from the routing protocols traceoptions statement included at the [edit routing-options] hierarchy level.

tunnel services—The Junos OS selects one of the available virtual tunnel (VT) interfaces to de-encapsulate the egress traffic.


RSVP is disabled.
