Maintenance Timer Expiry

The node MUST check to see if it knows of any other members of the cloud. If it does not, it MUST invoke the process as specified in section to attempt to discover the cloud.

In addition, the PNRP node MAY<4> resolve any PNRP IDs that it wants to learn additional route entries (for example, to ensure that the Route Cache contains entries roughly evenly distributed across the PNRP ID numbering space in order to reduce the time it takes to do a resolve on behalf of an application or higher-layer protocol). If it does so, then the ResolveReasonCode MUST be set to REASON_CACHE_MAINTENANCE.
