Feature Description
The PCF extends support to the Geographic Redundancy (GR) version of the Cisco Common Data Layer (CDL). When the primary CDL endpoint fails, PCF attempts the same operation on the next highly rated secondary endpoint thus providing a nondisrupted N7 or Diameter message handling. If the next rated endpoint is unavailable, then PCF reattempts the operation on the subsequent endpoint that has the highest rating and so on.
For more information on the CDL concepts, see the Ultra Cloud Core Common Data Layer Configuration Guide.
