Geographic Redundancy

The PCF extends support to the Geographic Redundancy (GR) version of the Cisco Common Data Layer (CDL). When the highest rated CDL endpoint fails, PCF attempts the same operation on the next highly rated CDL endpoint thus providing a nondisrupted 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.

PCF can handle issues of multiple CDL entry updates when multiple RxSTR received on PCF within a short gap.

Note

It is recommended to enable this feature after upgrading both local and remote sites to the latest PCF version.

For more information on the CDL concepts, see the Ultra Cloud Core Common Data Layer Configuration Guide.
