Configuring Support for Interworking Between RSVP Capable and RSVP Incapable Networks

The Support for Interworking Between RSVP Capable and RSVP Incapable Networks feature provides precondition-based Resource Reservation Protocol (RSVP) support for basic audio call and supplementary services on Cisco UBE. This feature improves the interoperability between RSVP and non-RSVP networks. RSVP functionality added to Cisco UBE helps you to reserve the required bandwidth before making a call.

This feature extends RSVP support to delayed-offer to delayed-offer and delayed-offer to early-offer calls, along with the early-offer to early-offer calls.

Finding Feature Information

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.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Prerequisites

  • RSVP policies allow you to configure separate bandwidth pools with varying limits so that any one application, such as video, can consume all the RSVP bandwidth on a specified interface at the expense of other applications, such as voice, which would be dropped.

  • To limit bandwidth per application, you must configure a bandwidth limit before configuring Support for the Interworking Between RSVP Capable and RSVP Incapable Networks feature. See the Configuring RSVP on an Interface task.

Cisco Unified Border Element

  • Cisco IOS Release 15.0(1)XA or a later release must be installed and running on your Cisco Unified Border Element.

Cisco Unified Border Element (Enterprise)

  • Cisco IOS XE Release <TBD> or a later release must be installed and running on your Cisco ASR 1000 Series Router.

Restrictions

The Support for Interworking Between RSVP Capable and RSVP Incapable Networks feature has the following restrictions:

  • Segmented RSVP is not supported.

  • Interoperability between Cisco UBE and Cisco Unified Communications Manager is not available.

  • RSVP-enabled video calls are not supported.

      Note   

      Configure the req-qos commandusing the same keyword that you used to configure the acc-qos command, either controlled-load or guaranteed-delay. That is, if you configured acc-qos controlled-load command in the previous step, then use the req-qos controlled-load command here.

       
      Step 6 end


      Example:
      Router(config-dial-peer)# end
       

      Exits dial peer voice configuration mode and returns to privileged EXEC mode.
