Chapter 62 Configuring RSVP
62.1 Overview
This chapter explains how to configure RSVP. For details about RSVP Command, see “RSVP Command” in
the “Network Protocol Command Reference”. For other document about Command, use index or type in
Command in online help.
Try to understand RSVP before configuring it, which would be helpful for users. RSVP protocol can be used
by a host to request a certain quality of business to an application data process. Routers can use RSVP
protocol to transfer quality of service request and carry out reservation. RSVP request is going to be reserved
on each node of data channels.
RSVP resource request is for single task data process. Logically, RSVP separates data sender and receiver,
despite sender and receiver are in the same application process. RSVP is above IP protocol. Although RSVP
does not transfer data, it belongs to Internet protocol (just like ICMP, IGMP or routing protocol). RSVP
implementation is like routing protocol and managing protocol.
RSVP is not a routing protocol; however RSVP is able to assist a current and future routing protocol. A routing
protocol decides how to transfer a data package, while RSVP deals with the Quality of Service (QoS) of the
transferred data packages.
RSVP and WFQ (weighted fair queuing) or RED (random early detection) coordinate and function together.
This kind of coordination contains two major concepts: use the RSVP flow between two ends, and use WFQ
dialog between two routers.

 Enable a RSVP on a Router
 Start RSVP in a IP Phone Module Configuration
 Use RSVP to configure Command
 Configure TOS and Precedence for RSVP flow
 Use access

62.3 RSVP Configuration Task
62.3.1 Enable a RSVP on a Router
To enable RSVP on a router, users must configure the interface for starting RSVP, which can be realized by
configure Command with interface on the RSVP. When the above configuration is done, RSVP protocol is able
to work on these interfaces.
Configure Network interface with RSVP and use the following Commands in interface configurations:
Command Function
ip rsvp bandwidth
[interface-kbps]
[single-flow-kbps]
Configure Network interface with RSVP
