Description
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).
Options
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.
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.
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-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.
Default
RSVP is disabled.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
