Usage Guidelines

Usage Scenario

A reservation style is the method used by an RSVP node to request an upstream ingress to reserve resources. The following styles are supported:

SE: explicitly reserves resources for one or more specified ingress nodes. The ingress nodes share reserved resources.
Fixed filter (FF): reserves resources for each ingress node. The sum of reserved resources on a node is equal to the sum of reserved resources for all ingress nodes.
The SE style is used to implement the make-before-break mechanism, whereas there is a few usage scenarios for the FF style.

Prerequisites

A P2MP tunnel template has been configured using the mpls te p2mp-template command.

Example

# Create a P2MP tunnel template named Template1 and set the resource reservation style to FF in the template view.
