Advanced RSVP-TE features
RSVP and RSVP-TE
Resource Reservation Protocol (RSVP) is used for reserving resources on each node along a path. RSVP
operates at the transport layer but does not participate in data transmission.
The following are features of RSVP:
• Unidirectional
• Receiver oriented. The receiver initiates resource reservation requests and is responsible for
maintaining the reservation information.
• Using soft state mechanism to maintain resource reservation information.
Extended RSVP can support MPLS label distribution and allow resource reservation information to be
transmitted with label bindings. This extended RSVP is called RSVP-TE, which is operating as a signaling
protocol for LSP tunnel setup in MPLS TE. RSVP-TE provides many configuration options with respect to
reliability, network resources, and other advanced features of MPLS TE.
Prerequisites for configuring RSVP TE advanced features
Before configuring RSVP-TE advanced features, do the following:
1. Configure MPLS basic capabilities.
