<p dir="ltr">Thank you for the response. <br>
Whether the forwarding is exactly in the following way?<br>
If say node A finds from LSDB that a data is found at say node F then it detects the next hop to reach F from routing table and forwards the interest to that next hop say B. Now, if the data is not found in the CS of B then again B finds from LSDB where the data can be found and again detects the next hop from routing table to reach to the data.</p>

<p>Yes It will be propagated the same way. </p>
<p>After A's neighbors update their LSA's as per A's, they will update their sync digest and respond to their neighbors' sync interest with the updated digest. Now A's neighbor's neighbors know there is a change in the LSDB and they will express interest to fetch
the update. This way the change will be propagated throughout the network.</p>

<p dir="ltr">Hello,<br>
Can you tell me whenever there is a change in LSA of a node A, it is updated in the neighbors of that node easily as there is periodic sync interest exchanged among the neighbors. Then how this change will be propagated to the neighbors of neighbors of A? In
the same way i.e. the neighbors of A replies to the sync interest from its neighbors with the change?</p>

<p dir="ltr">Hello,</p>
<p dir="ltr">Can anyone please tell me whether each router sends the periodic sync interests to all other routers in the network or only its direct neighbors? Is it a hop by hop notification when there is any updates? Or the node where the update occurred,
floods the update to all other nodes in a data packet?</p>

The sync interests are sent using a multicast strategy, but they should be aggregated when every node has the same sync digest (thus same interest). So when the network is stable, only one sync interest is sent per link per direction.
