3.1.4.3 Initiating a PNRP Synchronization Conversation

  • Article

A synchronization conversation allows a node to exchange resource information in the form of ROUTE_ENTRY structures with another given node in a given cloud.

The PNRP node MUST generate a random 16-byte nonce value, save it in its local Conversation nonce state, and then send to the given node a SOLICIT message that includes an SHA-1 [RFC3174] hash of the Conversation nonce in the Hashed Nonce field.

The node MUST save the Message ID of the SOLICIT message in the entry in the conversation table.

The node MUST also put the SOLICIT message in the Pending List, set its Retry Count to 2, and start its Message Retransmission Timer.
