Configuring RSVP Node ID Hellos
You can configure node-ID based RSVP hellos to ensure that Juniper Networks routers can interoperate with the equipment of other vendors. By default, the Junos OS uses interface-based RSVP hellos. Node-ID based RSVP hellos are specified in RFC 4558, Node-ID Based Resource Reservation Protocol (RSVP) Hello: A Clarification Statement. RSVP node-ID hellos are useful if you have configured BFD to detect problems over RSVP interfaces, allowing you to disable interface-hellos for these interfaces. You can also use node-ID hellos for graceful-restart procedures.
Node-ID hellos can be enabled globally for all RSVP neighbors. By default, node-ID hello support is disabled. If you have not enabled RSVP node IDs on the router, the Junos OS does not accept any node-ID hello packets.
To enable RSVP node-ID hellos globally on the router, include the node-hello statement:
You can include this statement at the following hierarchy levels:
- [edit protocols rsvp]
- [edit logical-systems logical-systems-name protocols rsvp]
You can also explicitly disable RSVP interface hellos globally. This type of configuration might be necessary in networks where the Juniper Networks router has numerous RSVP connections with equipment from other vendors. However, if you disable RSVP interface hellos globally, you can also configure a hello interval on an RSVP interface using the hello-interval statement. This configuration disables RSVP interface hellos globally, but enables RSVP interface hellos on the specified interface (the RSVP interface you configure the hello-interval statement on). This configuration might be necessary in a heterogeneous network in which some devices support RSVP node ID hellos and other devices support RSVP interface hellos.
To disable RSVP interface hellos globally on the router, include the no-interface-hello statement:
You can include this statement at the following hierarchy levels:
- [edit protocols rsvp]
- [edit logical-systems logical-systems-name protocols rsvp]
