RSVP Agents are basically Cisco IOS MTPs or transcoder devices which provide RSVP functionalities.
Check the user manual of the configured MTPs and transcoders to see whether they support RSVP
functionality. If none of them support RSVP functionality either they need to be upgraded (if upgraded
version support RSVP functionality) or additional MTP or transcoders need to be installed which support
RSVP functionality. If the RSVP Agent (MTP or transcoder) allocation is failing due to a capability
mismatch, it's possible that the media device does not support the requested capability (such as IPv4 to
IPv6 conversion, passthrough) or the capability might not be configured in the device. Please check the
user guide and documentation of the media device to make sure that device supports all the necessary
capabilities.
Also, caution should be taken care if all the MTP or transcoders are configured with all the supported
capabilities. There are certain capabilities (such as RFC 2833 DTMF or RFC 2833 DTMF passthrough
or passthrough) which could be supported by most of the MTPs or transcoders and there may be certain
capabilities (such as IPv4 to IPv6 conversion and vice versa or RSVP Agent functionality or Transfer
Relay Point or multimedia capability) which can be supported by only by a single MTP or transcoder
depending on the devices that you have.
For example, you may have end devices belonging to different locations and may need to reserve the
bandwidth only between two locations; calls between other locations may not need to reserve the
bandwidth. Now, suppose all the MTPs or transcoders are configured with all the supported capabilities
and only one MTP/transcoder supports RSVP functionality; if this MTP/transcoder is configured with
all the supported capabilities (which all the other MTPs or transcoders in the same MRGL or default
MRGL also support) it may happen that this MTP can get allocated for Transfer Relay Point or RFC 2833
DTMF or RFC 2833 DTMF passthrough or passthrough instead. As a result, when a need arises to
reserve the bandwidth (which other MTPs or transcoders in the same MRGL or default MRGL do not
support), all the resources of this MTP/transcoder may be in use and the RSVP Agent allocation may fail.
