Configuring RSVP-TE advanced features
RSVP-TE adds new objects in Path and Resv messages to support CR-LSP setup. RSVP-TE provides many
configurable options with respect to reliability, network resources, and other advanced features of MPLS
TE.
Before performing the configuration tasks in this section, be aware of each configuration objective and
its impact on your network.
Configuration prerequisites
Before configuring RSVP-TE advanced features, do the following:
• Configure MPLS basic capabilities
• Configure MPLS TE basic capabilities
• Establish an MPLS TE tunnel with RSVP-TE
Configuration procedure
Configuring RSVP reservation style
Each LSP set up using RSVP-TE is assigned a resource reservation style. During an RSVP session, the
receiver decides which reservation style can be used for this session and thus which LSPs can be used.
Currently, two reservation styles are available:
• Fixed-filter style (FF) where resources are reserved for individual senders and cannot be shared
among senders on the same session.
• Shared-explicit style (SE) where resources are reserved for senders on the same session and shared
among them.
