Usage Guidelines

Prerequisites

The RSVP Hello extension function has been enabled by running the mpls rsvp-te hello command.

Precautions

If the mpls rsvp-te hello full-gr command is run on an RSVP node, this node has the capability of RSVP GR Helper. If a node is a GR supporter rather than a GR node, run the mpls rsvp-te hello support-peer-gr command.

To change a node from a GR node to a GR supporter, you must run the undo mpls rsvp-te hello full-gr command, then run the mpls rsvp-te hello support-peer-gr command.
