The originating node create a route request message and broadcast the message, each intermediate node receiving the RREQ, and search in his route table to find destination if not founded With each new hop, the intermediate node adds its address to the routing request packet, therefore the packet size is increasing each time it is forwarded, then adding to its route table a path for the sender node, and finally the RREQ broadcasting again, While RREQ reaches its destination or an intermediate node that has a path to it, the RREP packet is created and sent back to the source.
With the signing of the agreement, the Angolan Flag Company (TAAG) and its counterpart, Singapore Airlines, have the right to operate with any type of aircraft at the points agreed in the route table (attached to the agreement), up to four weekly frequencies , with third and fourth freedoms for passenger services, which will be increased to seven weekly frequencies by 2023.

In (5), C is the count of route table entries in all switches (which can be easily recorded by the U-TRI server when route tables are created and updated).
Node E looks into the route table. If the path from node E to node F is valid, then node E replies RERREP(route repair reply packet).
This protocol adds a new attribute, sequence number, to each route table entry at each node.
Further, in order to process the RREQ, the node sets up a reverse route entry for the source node in its route table. This reverse route entry contains the source nodes IP address and the sequence number as well as the number of hops to the source node and the IP addresses of the neighbor from which the RREQ was received.
On its way through the network, the RREQ message initiates creation of temporary route table entries for the reverse route in the nodes it passes.
According to the selection process of BGP routing, in the first step of the route table, the best routing has been selected from a number of candidates of routers.
Each node sets up a route table and a spare route table after it receives a valid reply packet.
