Configuring an RSVP GR Helper

Configuring an RSVP GR Helper

An RSVP GR Helper is configured to allow devices along an RSVP-TE tunnel to retain RSVP sessions during a master/backup switchover.

Usage Scenario

The NE40E can only function as a GR Helper to help a neighbor node to complete RSVP GR. The RSVP GR Helper needs to be configured only after GR is enabled on the neighbor node that supports the RSVP GR Restarter. If a local device is only connected to NE40Es running the same version with the local device, there is no need to configure the RSVP GR Helper on the local device.

Pre-configuration Tasks

Before configuring an RSVP GR Helper, configure an RSVP-TE tunnel.
