mpls rsvp signalling node-hello
Syntax
{ ip | mpls } rsvp signalling node-hello
[ refresh { interval
helloInterval | misses helloMisses } ]
{ no | default } { ip | mpls } rsvp signalling node-hello
Release Information
Command introduced in JUNOSe Release 9.0.0.
Description
Turns on or configures RSVP-TE hellos to include node IDs as source and destination
addresses in the hello packets for all RSVP-TE interfaces on the current virtual router.
RSVP-TE hellos based on node ID enable the JUNOSe software to interoperate its
RSVP-TE graceful restart capability with routers that cannot support RSVP-TE graceful
restart with link-based hellos.
The no version turns off node-hello support on the current VR. The default version
restores the default configuration, in which RSVP node hello support is not enabled.
NOTE: Node hellos are required only for interoperability with some non–E Series
implementations. Node hellos are not required for communications between routers
running JUNOSe software or for interoperability with routers running JUNOS software.
Options
ip—Specifies alternative keyword for compatibility with non–E Series
