When an OSPF network is converged and no network topology change has been detected by a router, how often are LSU packets sent to neighboring routers?

When an OSPF network is converged and no network topology change has been detected by a router, how often are LSU packets sent to neighboring routers?

• Every 10 seconds
• Every 40 seconds
• Every 15 minutes
• Every 30 minutes

Explanation: After all LSRs have been satisfied for a given router, the adjacent routers are considered synchronized and in a Full state. Updates (LSUs) are sent to neighbors only under the following conditions:

• When a network topology change is detected (incremental updates)
• Every 30 minutes
