The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Resource Reservation Protocol (RSVP) over UDP feature provides the capability for routers to enable neighbor routers to process and send RSVP control packets over UDP. With the implementation of the RSVP over UDP feature, the RSVP protocol stack is enhanced to support processing of RSVP control messages over UDP and raw IP.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

The RSVP over UDP feature addresses the following scenarios:
This task starts RSVP and sets the bandwidth and single-flow limits. By default, RSVP is disabled so that it is backward compatible with systems that do not implement RSVP. To enable RSVP for IP on an interface, perform the following task.
1.
enable
2.
configure
terminal
3.
interface
type
number
4.
ip
rsvp
bandwidth
[interface-bandwidth
[percent
percent-bandwidth | [single-flow-bandwidth] [sub-pool
bandwidth]]]
5.
end
To enable RSVP over UDP, perform the following task:
1.
enable
2.
configure
terminal
3.
ip
rsvp
udp
neighbor
neighbor-IP-address
router [vrf
vrf-name]
4.
end
The following example shows how to enable RSVP for IP on an interface:
enable configure terminal interface fastethernet 0/1 ip rsvp bandwidth 23 54 end
The following example shows how to configure the RSVP over UDP feature on a neighbor router:
enable configure terminal ip rsvp udp neighbor 10.1.1.1 router vrf vrf-1 end
