[ 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 implementations
• helloInterval—Number of milliseconds specifying the interval at which node hellos are sent, in the range 1000–60000; default value is 10000
• helloMisses—Number of RSVP-TE node hello messages from a peer that can be missed before that hello adjacency peer is considered to be down, in the range 4–10; default value is 4
